This might fix test failures that have been reported on some platforms. 2.21 Regression tests are now functional for versions of libgd compiled exclusively with PNG, JPEG or GIF support. 2.20 GD::Image->newFromGdData() and newFromGd2Data() got broken somewhere along the line. They are now fixed (and have a regression test).

Added extended options to stringFT(). Added filledArc(), ellipse() and filledEllipse() methods. Added command-line options to Makefile.PL provided by David Eisenberg. 2.06 Added saveAlpha() and alphaBlending() methods. 2.05 Alpha methods courtesy Georges Arnould. 2.041 Added a regression test to detect certain versions of freetype. 2.04 Removed the patch file since Tom has begun adding his own configure file. Changed the context member from free to gd_free to allow for compiling. Fixed the regression tests since the gd-generated images have changed slightly. 2.03 Skipped so as to remain version number compatible with libgd. 2.02 Changed Math::Trig version requirement from 0.0 to 1.0 as Perl 5.8 no long recognizes this as a valid version number. 2.01 Added Math::Trig to the prerequisites because GD::Polyline needs it. 2.00 Folded in support for gd version 2.0 from Dan Palermo Folded in support for splines (GD::Polyline) from Dan Harasty. Removed all GIF support. 1.43 Added demo of Type1 fonts to truetype demo from Slaven Rezic. 1.42 Fixed the patch_gd.pl file Version 2.0 is coming. 1.39 Fixed FreeType test, at least on some platforms.

ABSTRACT: This is a autoloadable interface module for libgd, a popular library for creating and manipulating PNG files. With this library you can create PNG images on the fly or modify existing files. Features include: a. lines, polygons, rectangles and arcs, both filled and unfilled b. flood fills c. the use of arbitrary images as brushes and as tiled fill patterns d. line styling (dashed lines and the like) e. horizontal and vertical text rendering f. support for transparency and interlacing g. support for TrueType font rendering, via libfreetype. h. support for spline curves, via GD::Polyline i. support for symbolic font names, such as "helvetica:italic" j. support for symbolic color names, such as "green", via GD::Simple k. produces output in png, gif, jpeg, xbm and other formats supported by libgd l. produces output in svg format via GD::SVG. For full information on usage, see the accompanying man and html documentation. Also check the FAQ at the bottom of this document. INSTALLATION: 1. Windows users can find a binary PPM package in the repositories at these sites: http://trouchelle.com/perl/ppmrepview.pl http://www.bribes.org/perl/ppmdir.html These packages are not always updated to the most recent version, but GD is pretty stable and you usually won't miss the bleeding edge version. For Unix/darwin users and those who have a developer's kit installed on Windows (e.g. cygwin): 2. Make sure you have downloaded and installed the following packages: a. Perl 5.6.0 or higher: http://www.perl.com/ b. The gd graphics library: http://libgd.org c. The PNG graphics library: http://www.libpng.org/pub/png/libpng.html d. The zlib compression library: http://www.gzip.org/zlib/ (OPTIONAL) e. The FreeType font rendering library for TrueType fonts: http://www.freetype.org/ f. The JPEG library, version 6b or later: ftp://ftp.uu.net/graphics/jpeg/ g. The XPM library, a standard part of modern X Windows distributions. If you don't have a modern version of X, don't try to get XPM working. 3. On darwin, you can use these package managers to resolve dependencies and build libgd: i. MacPorts http://www.macports.org/ ii. Homebrew http://mxcl.github.io/homebrew/ If this module fails to compile and link, you are probably using an older version of libgd. Symptoms of this problem include errors about functions not being recognized in the gd.h header file, and undefined symbols from the linker. If you are having this type of error, please REMOVE all versions of libgd, gd.h from your system and reinstall libgd 2.0.28 or higher. Do not contact Lincoln for help until you have done this. Use GD 1.41 for libgd versions 1.8.4 and lower. 3. Unpack the tar file: zcat GD-2.XX.tar.gz | tar xvf - (Where "XX" is the most recent revision number.) This will create the directory GD-2.XX. 4. To compile GD.pm: a. cd GD-2.XX b. perl Makefile.PL c. make d. make test f. sudo make install This will create GD.pm and install it into the system-wide Perl library directory. You'll need root privileges to do the install step. If you don't have them, see below. During step (b), Makefile.PL will look for the program gdlib-config or gdlib.pc that newer versions of libgd install for you. If this program is not present, the Makefile.PL script will ask you whether to build support for JPEG, FreeType and/or XPM image formats. Please answer "y" (the default) if libgd was built with the feature, and "n" if it was not. Failure to answer correctly will lead to link errors. If, during step (b) you see notes about missing libraries, then this module will probably not link correctly, even though the warning may say "probably harmless". 5. Before you install GD, you will want to run the regression tests. You can do this after the "make" step by typing: make test 6. There are some demos you can run in ext/GD/demos. They print PNG files to standard output. To view the files, pipe their output to "display" or "xv" in this way: a. cd GD-2.XX/demos b perl shapes.pl | display - You will need a graphics program that can read and display PNG format. I recommend Image::Magick's display program, available from ftp://ftp.wizards.dupont.com/pub/ImageMagick/ If you don't have any display programs handy, you can save to a temporary file and display with recent versions of Netscape or Internet Explorer. 7. A program named fonttest is included in this package under demos. This generates an image showing all the built-in fonts available. If you have built libgd with TrueType support, and you have a directory containing some TrueType fonts, you can create a simple font listing by running the program truetype_test, also located in demos. 8. See demos/gd_example.cgi for an example of how to use GD to create a picture dynamically with a CGI script. It's intended to be run under a Web server. To see it work, install it in your server's cgi-bin/ directory and invoke it from a browser by fetching a URL like: http://your.site/cgi-bin/gd_example.cgi IF YOU RUN INTO PROBLEMS If the make and install all seem to go well but you get errors like "Fatal error: can't load module GD.so", or "Fatal error: unknown symbol gdFontSmall" when you try to run a script that uses GD, you may have problems with dynamic linking. Check whether other dynamically-linked Perl modules such as POSIX and DB_File run correctly. If not, then you'll have to link Perl statically, as described above. Other problems may be fixed by compiling libgd as a shared library, as described in step (2) of the installation instructions. If you are trying to compile and link GD on a Windows or Macintosh machine and fail, please verify that you are able to build the Perl distribution from source code. If you can't do that, then you don't have the compiler/linker/make tools required for building Perl modules. You may not even need to do this, as ActiveState and MacPerl both include precompiled versions of GD. If you have problems and can't solve it on your own, post a message to the newsgroup "comp.lang.perl.modules". There are some systems that require obscure compiler and linker options in order to compile correctly, and unfortunately I have a limited number of systems at my disposal. You're much more likely to get correct answers from the gurus on the newsgroup than from myself. THE GD::SIMPLE LIBRARY GD::Simple is a simplified API for GD. It supports turtle graphics, a unified interface for drawing text, and symbolic color names (like "green"). Run "perldoc GD::Simple" for information on using it. The GD::SVG LIBRARY GD::SVG, which is available separately on CPAN, provides a subset of GD method calls. For this subset, you can create images in SVG (scalable vector graphics) format. THE QUICKDRAW LIBRARY This is no longer supported. FREQUENTLY ASKED QUESTIONS 1. I get a warning about prerequisite Math::Trig not being found The version of Math::Trig that comes with Perl version 5.6.0 and lower has a bug in it that causes it not to be found even when it is installed. Try running perl -MMath::Trig -e0 from the command line. If you get no errors, go ahead and install GD. If you get an error, install Math::Trig from CPAN. 2. Why do I get errors about functions not being found when building this module? You need libgd (the C library that does all the work) version 2.0.28 or higher. Older versions will give you errors during GD installation. Get the latest version from http://libgd.org and install it. Sometimes just installing the new version of libgd is not enough: you must remove the old library first. Find the gd.h include file and all libgd files and remove them from your system. 3. Why do I get errors about symbols being undefined when building this module? See (1). 4. The %&#&#! thing doesn't compile at all! I'm getting lots of compile errors! Does "make" fail with messages like these? GD.xs: In function 'newDynamicCtx': GD.xs:440: error: 'gdIOCtx' has no member named 'gd_free' GD.xs: In function 'gd_cloneDim': GD.xs:460: error: 'struct gdImageStruct' has no member named 'alpha' GD.xs:460: error: 'struct gdImageStruct' has no member named 'alpha' GD.xs:466: error: 'struct gdImageStruct' has no member named 'thick' GD.xs:466: error: 'struct gdImageStruct' has no member named 'thick' If so, then you may have an old gd.h include file located somewhere in your system include path. Please find it and remove it. A typical location is /usr/include/gd.h. The way to make sure you are removing the correct gd.h is to run "gdlib-config --cflags" to find out where the current gd.h lives: % gdlib-config --cflags -I/usr/local/include This tells you that /usr/local/include/gd.h is the correct gd.h. Please find and remove any other gd.h. 5. My scripts fail with "Can't locate object method 'png' via package "GD::Image". libgd can now be built with support for one or more of the PNG, GIF, XPM or JPEG formats. If one or more of these formats are not supported by libgd, then the corresponding GD::Image methods will be unavailable. Unfortunately, many older scripts assume that the png() method will always be present. You can work around this issue with code like the following: my $image = $gd->can('png') ? $gd->png : $gd->gif; or if you prefer eval {} my $image = eval {$gd->png} || $gd->gif; As of libgd 2.0.33, GIF support is always compiled in, so (for the time being!) this is a safe fallback. 6. Is there a utility to convert X Windows BDF fonts into GD fonts. Yes. See the utility bdf2gdfont.pl. Run "bdf2gdfont.pl -h" to get help on using this. 7. Does GD run with Macintosh OS X? Yes. GD compiles just fine under OSX. However, you may need to remove old versions of libgd, libpng, and libz and reinstall the current versions before you try to install GD. 8. Does GD run with Win32 Perl? The latest ActiveState binaries for Win32 systems come with GD already compiled in and ready to go. I don't own any Win32 systems, and cannot provide you with help in compiling GD from scratch on such systems. Github actions and appveyor are used to test the windows builds. 9. GD won't compile on system XX. Because libgd relies on multiple external libraries, GD does as well. Unfortunately, different systems place their libraries in different places and sometimes are picky about the order in which libraries are linked. The best thing to do is to install the latest version of libgd. Recent versions of libgd contain a gdlib-config utility, which GD will use to determine which libraries are necessary and in which order to link them. Another thing to be aware of is that some Unix distributions provide a faulty precompiled version of Perl which is unable to build and load new C-based modules (like this one). If you are getting errors like this: /arch/auto/GD/GD.so: undefined symbol: SetCPerlObj at .... then you may have such a faulty version of Perl. The most reliable thing to do is to recompile Perl from source code, thereby ensuring that it is complete. 10. When I try to load an XPM file, all I get is blackness! The libgd createFromXpm() function works with some XPM files, and not with others. The problem is buried deep in the libXpm library somewhere. 11. The stringFTCircle() method doesn't work! I know. I think this might be a problem in libgd because I have never gotten it to work as a C program. If you have any insight into this problem let me know. 12. Test XX fails The regression tests for GD involve generating images, saving them as PNG, JPEG or GIF files, and then comparing the files bit-for-bit to known "correct" files. Sometimes one of the underlying C libraries such as libz, libpng or libgd is updated, causing GD to generate an image that is subtly different. These differences are usually insignificant, such as a reordering of colors in the color table, but they will call isolated tests to fail. If you are seeing the great majority of GD tests pass, but one or two fail, then you are probably seeing the effect of a new library. Just go ahead and install GD and drop me a note about the problem.

GD allows you to create color drawings using a large number of graphics primitives, and emit the drawings as PNG files. GD defines the following four classes: =over 5 =item C An image class, which holds the image data and accepts graphic primitive method calls. =item C A font class, which holds static font information and used for text rendering. =item C A simple polygon object, used for storing lists of vertices prior to rendering a polygon into an image. =item C A "simple" class that simplifies the GD::Image API and then adds a set of object-oriented drawing methods using turtle graphics, simplified font handling, ability to work in polar coordinates, HSV color spaces, and human-readable color names like "lightblue". Please see L for a description of these methods. =back A Simple Example: #!/usr/bin/perl use GD; # create a new image $im = GD::Image->new(100,100); # allocate some colors $white = $im->colorAllocate(255,255,255); $black = $im->colorAllocate(0,0,0); $red = $im->colorAllocate(255,0,0); $blue = $im->colorAllocate(0,0,255); # make the background transparent and interlaced $im->transparent($white); $im->interlaced('true'); # Put a black frame around the picture $im->rectangle(0,0,99,99,$black); # Draw a blue oval $im->arc(50,50,95,75,0,360,$blue); # And fill it with red $im->fill(50,50,$red); # make sure we are writing to a binary stream binmode STDOUT; # Convert the image to PNG and print it on standard output print $im->png; Notes: =over 5 =item 1. To create a new, empty image, send a new() message to GD::Image, passing it the width and height of the image you want to create. An image object will be returned. Other class methods allow you to initialize an image from a preexisting JPG, PNG, GD, GD2, XBM or other supported image files. =item 2. Next you will ordinarily add colors to the image's color table. colors are added using a colorAllocate() method call. The three parameters in each call are the red, green and blue (rgb) triples for the desired color. The method returns the index of that color in the image's color table. You should store these indexes for later use. =item 3. Now you can do some drawing! The various graphics primitives are described below. In this example, we do some text drawing, create an oval, and create and draw a polygon. =item 4. Polygons are created with a new() message to GD::Polygon. You can add points to the returned polygon one at a time using the addPt() method. The polygon can then be passed to an image for rendering. =item 5. When you're done drawing, you can convert the image into PNG format by sending it a png() message (or any other supported image format). It will return a (potentially large) scalar value containing the binary data for the image. Ordinarily you will print it out at this point or write it to a file. To ensure portability to platforms that differentiate between text and binary files, be sure to call C on the file you are writing the image to. =back =head1 Object Constructors: Creating Images See L for the current list of supported Image formats. The following class methods allow you to create new GD::Image objects. =over 4 =item B<$image = GD::Image-Enew([$width,$height],[$truecolor])> =item B<$image = GD::Image-Enew(*FILEHANDLE)> =item B<$image = GD::Image-Enew($filename)> =item B<$image = GD::Image-Enew($data)> The new() method is the main constructor for the GD::Image class. Called with two integer arguments, it creates a new blank image of the specified width and height. For example: $myImage = GD::Image->new(100,100) || die; This will create an image that is 100 x 100 pixels wide. If you don't specify the dimensions, a default of 64 x 64 will be chosen. The optional third argument, $truecolor, tells new() to create a truecolor GD::Image object. Truecolor images have 24 bits of color data (eight bits each in the red, green and blue channels respectively), allowing for precise photograph-quality color usage. If not specified, the image will use an 8-bit palette for compatibility with older versions of libgd. Alternatively, you may create a GD::Image object based on an existing image by providing an open filehandle, a filename, or the image data itself. The image formats automatically recognized and accepted are: GIF, PNG, JPEG, XBM, XPM, BMP, GD2, TIFF, WEBP, HEIF or AVIF. Other formats, including WBMP, and GD version 1, cannot be recognized automatically at this time, only by filename. If something goes wrong (e.g. insufficient memory), this call will return undef. =item B<$image = GD::Image-EtrueColor([0,1])> For backwards compatibility with scripts previous versions of GD, new images created from scratch (width, height) are palette based by default. To change this default to create true color images use: GD::Image->trueColor(1); before creating new images. To switch back to palette based by default, use: GD::Image->trueColor(0); =item B<$image = GD::Image-EnewPalette([$width,$height])> =item B<$image = GD::Image-EnewTrueColor([$width,$height])> The newPalette() and newTrueColor() methods can be used to explicitly create an palette based or true color image regardless of the current setting of trueColor(). =item B<$image = GD::Image-EnewFromPng($file, [$truecolor])> =item B<$image = GD::Image-EnewFromPngData($data, [$truecolor])> The newFromPng() method will create an image from a PNG file read in through the provided filehandle or file path. The filehandle must previously have been opened on a valid PNG file or pipe. If successful, this call will return an initialized image which you can then manipulate as you please. If it fails, which usually happens if the thing at the other end of the filehandle is not a valid PNG file, the call returns undef. Notice that the call doesn't automatically close the filehandle for you. But it does call C for you, on platforms where this matters. You may use any of the following as the argument: 1) a simple filehandle, such as STDIN 2) a filehandle glob, such as *PNG 3) a reference to a glob, such as \*PNG 4) an IO::Handle object 5) the pathname of a file In the latter case, newFromPng() will attempt to open the file for you and read the PNG information from it. Example1: open (PNG,"barnswallow.png") || die; $myImage = GD::Image->newFromPng(\*PNG) || die; close PNG; Example2: $myImage = GD::Image->newFromPng('barnswallow.png'); To get information about the size and color usage of the information, you can call the image query methods described below. Images created by reading PNG images will be truecolor if the image file itself is truecolor. To force the image to be palette-based, pass a value of 0 in the optional $truecolor argument. The newFromPngData() method will create a new GD::Image initialized with the PNG format B contained in C<$data>. =item B<$image = GD::Image-EnewFromJpeg($file, [$truecolor])> =item B<$image = GD::Image-EnewFromJpegData($data, [$truecolor])> These methods will create an image from a JPEG file. They work just like newFromPng() and newFromPngData(), and will accept the same filehandle and pathname arguments. Images created by reading JPEG images will always be truecolor. To force the image to be palette-based, pass a value of 0 in the optional $truecolor argument. =item B<$image = GD::Image-EnewFromGif($file, [$truecolor])> =item B<$image = GD::Image-EnewFromGifData($data)> These methods will create an image from a GIF file. They work just like newFromPng() and newFromPngData(), and will accept the same filehandle and pathname arguments. Images created from GIFs are always 8-bit palette images. To convert to truecolor, you must create a truecolor image and then perform a copy. =item B<$image = GD::Image-EnewFromXbm($file, [$truecolor])> This works in exactly the same way as C, but reads the contents of an X Bitmap (black & white) file: open (XBM,"coredump.xbm") || die; $myImage = GD::Image->newFromXbm(\*XBM) || die; close XBM; There is no newFromXbmData() function, because there is no corresponding function in the gd library. =item B<$image = GD::Image-EnewFromWBMP($file)> This works in exactly the same way as C, but reads the contents of a Wireless Application Protocol Bitmap (WBMP) file: open (WBMP,"coredump.wbmp") || die; $myImage = GD::Image->newFromWBMP(\*WBMP) || die; close WBMP; There is no newFromWBMPData() function, because there is no corresponding function in the gd library. =item B<$image = GD::Image-EnewFromBmp($file)> This works in exactly the same way as C, but reads the contents of a Windows Bitmap (BMP) file: open (BMP,"coredump.bmp") || die; $myImage = GD::Image->newFromBmp(\*BMP) || die; close BMP; There is no newFromBmpData() function, because there is no corresponding function in the gd library. =item B<$image = GD::Image-EnewFromGd($file)> =item B<$image = GD::Image-EnewFromGdData($data)> NOTE: GD and GD2 support was dropped witn libgd 2.3.2. These methods initialize a GD::Image from a Gd file, filehandle, or data. Gd is Tom Boutell's disk-based storage format, intended for the rare case when you need to read and write the image to disk quickly. It's not intended for regular use, because, unlike PNG or JPEG, no image compression is performed and these files can become B. $myImage = GD::Image->newFromGd("godzilla.gd") || die; close GDF; =item B<$image = GD::Image-EnewFromGd2($file)> =item B<$image = GD::Image-EnewFromGd2Data($data)> NOTE: GD and GD2 support was dropped witn libgd 2.3.2. This works in exactly the same way as C and newFromGdData, but use the new compressed GD2 image format. =item B<$image = GD::Image-EnewFromGd2Part($file,srcX,srcY,width,height)> This class method allows you to read in just a portion of a GD2 image file. In addition to a filehandle, it accepts the top-left corner and dimensions (width,height) of the region of the image to read. For example: open (GDF,"godzilla.gd2") || die; $myImage = GD::Image->newFromGd2Part(\*GDF,10,20,100,100) || die; close GDF; This reads a 100x100 square portion of the image starting from position (10,20). =item B<$image = GD::Image-EnewFromXpm($filename)> This creates a new GD::Image object starting from a B. This is unlike the other newFrom() functions because it does not take a filehandle. This difference comes from an inconsistency in the underlying gd library. $myImage = GD::Image->newFromXpm('earth.xpm') || die; This function is only available if libgd was compiled with XPM support. NOTE: The libgd library is unable to read certain XPM files, returning an all-black image instead. =item B<$bool = GD::supportsFileType($filename, $is_writing)> This returns a TRUE or FALSE value, if libgd supports reading or when the 2nd argument is 1, if libgd supports writing the given filetype, depending on the filename extension. Only with libgd versions E= gd-2.1.1. Assuming LibGD is compiled with support for these image types, the following extensions are supported: .gif .gd, .gd2 .wbmp .bmp .xbm .tga .png .jpg, .jpeg .tiff, .tif .webp .heic, .heix .avif .xpm Filenames are parsed case-insensitively. .avifs is not yet suppurted upstream in libavif. =back =head1 GD::Image Methods Once a GD::Image object is created, you can draw with it, copy it, and merge two images. When you are finished manipulating the object, you can convert it into a standard image file format to output or save to a file. =head2 Image Data Output Methods The following methods convert the internal drawing format into standard output file formats. =over =item B<$pngdata = $image-Epng([$compression_level])> This returns the image data in PNG format. You can then print it, pipe it to a display program, or write it to a file. Example: $png_data = $myImage->png; open (DISPLAY,"| display -") || die; binmode DISPLAY; print DISPLAY $png_data; close DISPLAY; Note the use of C. This is crucial for portability to DOSish platforms. The optional $compression_level argument controls the amount of compression to apply to the output PNG image. Values range from 0-9, where 0 means no compression (largest files, highest quality) and 9 means maximum compression (smallest files, worst quality). A compression level of -1 uses the default compression level selected when zlib was compiled on your system, and is the same as calling png() with no argument. Be careful not to confuse this argument with the jpeg() quality argument, which ranges from 0-100 and has the opposite meaning from compression (higher numbers give higher quality). =item B<$gifdata = $image-Egifanimbegin([$GlobalCM [, $Loops]])> For libgd version 2.0.33 and higher, this call begins an animated GIF by returning the data that comprises animated gif image file header. After you call this method, call gifanimadd() one or more times to add the frames of the image. Then call gifanimend(). Each frame must be the same width and height. A typical sequence will look like this: my $gifdata = $image->gifanimbegin; $gifdata .= $image->gifanimadd; # first frame for (1..100) { # make a frame of right size my $frame = GD::Image->new($image->getBounds); add_frame_data($frame); # add the data for this frame $gifdata .= $frame->gifanimadd; # add frame } $gifdata .= $image->gifanimend; # finish the animated GIF print $gifdata; # write animated gif to STDOUT If you do not wish to store the data in memory, you can print it to stdout or a file. The image that you call gifanimbegin on is used to set the image size, color resolution and color map. If argument $GlobalCM is 1, the image color map becomes the GIF89a global color map. If $Loops is given and >= 0, the NETSCAPE2.0 application extension is created, with looping count. Looping count 0 means forever. =item B<$gifdata = $image-Egifanimadd([$LocalCM [, $LeftOfs [, $TopOfs [, $Delay [, $Disposal [, $previm]]]]]])> Returns the data that comprises one animated gif image frame. You can then print it, pipe it to a display program, or write it to a file. With $LeftOfs and $TopOfs you can place this frame in different offset than (0,0) inside the image screen. Delay between the previous frame and this frame is in 1/100s units. Disposal is usually and by default 1. Compression is activated by giving the previous image as a parameter. This function then compares the images and only writes the changed pixels to the new frame in animation. The Disposal parameter for optimized animations must be set to 1, also for the first frame. $LeftOfs and $TopOfs parameters are ignored for optimized frames. =item B<$gifdata = $image-Egifanimend()> Returns the data for end segment of animated gif file. It always returns string ';'. This string must be printed to an animated gif file after all image frames to properly terminate it according to GIF file syntax. Image object is not used at all in this method. =item B<$jpegdata = $image-Ejpeg([$quality])> This returns the image data in JPEG format. You can then print it, pipe it to a display program, or write it to a file. You may pass an optional quality score to jpeg() in order to control the JPEG quality. This should be an integer between 0 and 100. Higher quality scores give larger files and better image quality. If you don't specify the quality, jpeg() will choose a good default. =item B<$gifdata = $image-Egif()>. This returns the image data in GIF format. You can then print it, pipe it to a display program, or write it to a file. =item B<$gddata = $image-Egd> This returns the image data in GD format. You can then print it, pipe it to a display program, or write it to a file. Example: binmode MYOUTFILE; print MYOUTFILE $myImage->gd; =item B<$gd2data = $image-Egd2> Same as gd(), except that it returns the data in compressed GD2 format. =item B<$bmpdata = $image-Ebmp([$compression])> This returns the image data in BMP format, which is a Windows Bitmap. If compression is set to 1, it will use RLE compression on the pixel data; otherwise, setting it to 0 (the default) will leave the BMP pixel data uncompressed. =item B<$wbmpdata = $image-Ewbmp([$foreground])> This returns the image data in WBMP format, which is a black-and-white image format. Provide the index of the color to become the foreground color. All other pixels will be considered background. =item B<$tiffdata = $image-Etiff()> This returns the image data in TIFF format. =item B<$webpdata = $image-Ewebp([$quality])> This returns the image data in WEBP format, with the optional quality argument. The default is 80, also chosen by the value -1. A quality value of >= 101 is considered Lossless. =item B<$webpdata = $image-Eheif([$quality])> This returns the truecolor image data in HEIF format, with the optional quality and speed arguments. If truecolor is not set, this fails. The default quality is 80, also chosen by the value -1. A quality value of 200 is considered Lossless. =item B<$webpdata = $image-Eavif([$quality,$speed])> This returns the truecolor image data in AVIF format, with the AVif encoder and 444 chroma, and the optional quality argument. If truecolor is not set, this fails. The default compression quality 1-100 is -1, the default speed 0-10 is 6. =item B<$success = $image-E_file($filename)> Writes an image to a file in the format indicated by the filename, with libgd versions E= gd-2.1.1. File type is determined by the extension of the file name. See C for an overview of the parsing. For file types that require extra arguments, C<_file> attempts to use sane defaults: C chunk size = 0, compression is enabled. C quality = -1 (i.e. the reasonable default) C foreground is the darkest available color C quality default C quality default, codes = HEVC, chroma = 444 C quality default, speed = 6 Everything else is called with the two-argument function and so will use the default values. C<_file> and the underlying libgd C has some rudimentary error detection and will return FALSE (0) if a detectable error occurred. However, the image loaders do not normally return their error status so a result of TRUE (1) does **not** mean the file was saved successfully. =back =head2 Color Control These methods allow you to control and manipulate the GD::Image color table for palette, non-truecolor images. =over 4 =item B<$index = $image-EcolorAllocate(red,green,blue)> This allocates a color with the specified red, green and blue components and returns its index in the color table, if specified. The first color allocated in this way becomes the image's background color. (255,255,255) is white (all pixels on). (0,0,0) is black (all pixels off). (255,0,0) is fully saturated red. (127,127,127) is 50% gray. You can find plenty of examples in /usr/X11/lib/X11/rgb.txt. If no colors are allocated, then this function returns -1. Example: $black = $myImage->colorAllocate(0,0,0); #background color $white = $myImage->colorAllocate(255,255,255); $peachpuff = $myImage->colorAllocate(255,218,185); =item B<$index = $image-EcolorAllocateAlpha(reg,green,blue,alpha)> This allocates a color with the specified red, green, and blue components, plus the specified alpha channel. The alpha value may range from 0 (opaque) to 127 (transparent). The C function changes the way this alpha channel affects the resulting image. =item B<$image-EcolorDeallocate(colorIndex)> This marks the color at the specified index as being ripe for reallocation. The next time colorAllocate is used, this entry will be replaced. You can call this method several times to deallocate multiple colors. There's no function result from this call. Example: $myImage->colorDeallocate($peachpuff); $peachy = $myImage->colorAllocate(255,210,185); =item B<$index = $image-EcolorClosest(red,green,blue)> This returns the index of the color closest in the color table to the red green and blue components specified. If no colors have yet been allocated, then this call returns -1. Example: $apricot = $myImage->colorClosest(255,200,180); =item B<$index = $image-EcolorClosestAlpha(red,green,blue,alpha)> This returns the index of the color closest in the color table to the red green blue and alpha components specified. If no colors have yet been allocated, then this call returns -1. Example: $apricot = $myImage->colorClosestAlpha(255,200,180,0); =item B<$index = $image-EcolorClosestHWB(red,green,blue)> This also attempts to return the color closest in the color table to the red green and blue components specified. It uses a Hue/White/Black color representation to make the selected color more likely to match human perceptions of similar colors. If no colors have yet been allocated, then this call returns -1. Example: $mostred = $myImage->colorClosestHWB(255,0,0); =item B<$index = $image-EcolorExact(red,green,blue)> This returns the index of a color that exactly matches the specified red green and blue components. If such a color is not in the color table, this call returns -1. $rosey = $myImage->colorExact(255,100,80); warn "Everything's coming up roses.\n" if $rosey >= 0; =item B<$index = $image-EcolorExactAlpha(red,green,blue,alpha)> This returns the index of a color that exactly matches the specified red green blue and alpha components. If such a color is not in the color table, this call returns -1. $rosey = $myImage->colorExactAlpha(255,100,80,0); warn "Everything's coming up roses.\n" if $rosey >= 0; =item B<$index = $image-EcolorResolve(red,green,blue)> This returns the index of a color that exactly matches the specified red green and blue components. If such a color is not in the color table and there is room, then this method allocates the color in the color table and returns its index. $rosey = $myImage->colorResolve(255,100,80); warn "Everything's coming up roses.\n" if $rosey >= 0; =item B<$index = $image-EcolorResolveAlpha(red,green,blue,alpha)> This returns the index of a color that exactly matches the specified red green blue and alpha components. If such a color is not in the color table and there is room, then this method allocates the color in the color table and returns its index. $rosey = $myImage->colorResolveAlpha(255,100,80,0); warn "Everything's coming up roses.\n" if $rosey >= 0; =item B<$colorsTotal = $image-EcolorsTotal> I This returns the total number of colors allocated in the object. $maxColors = $myImage->colorsTotal; In the case of a TrueColor image, this call will return undef. =item B<$index = $image-EgetPixel(x,y)> I This returns the color table index underneath the specified point. It can be combined with rgb() to obtain the rgb color underneath the pixel. Example: $index = $myImage->getPixel(20,100); ($r,$g,$b) = $myImage->rgb($index); =item B<($red,$green,$blue) = $image-Ergb($index)> This returns a list containing the red, green and blue components of the specified color index. Example: @RGB = $myImage->rgb($peachy); =item B<($alpha) = $image-Ealpha($index)> This returns an item containing the alpha component of the specified color index. Example: @RGB = $myImage->rgb($peachy); =item B<$image-Etransparent($colorIndex)> This marks the color at the specified index as being transparent. Portions of the image drawn in this color will be invisible. This is useful for creating paintbrushes of odd shapes, as well as for making PNG backgrounds transparent for displaying on the Web. Only one color can be transparent at any time. To disable transparency, specify -1 for the index. If you call this method without any parameters, it will return the current index of the transparent color, or -1 if none. Example: open(PNG,"test.png"); $im = GD::Image->newFromPng(PNG); $white = $im->colorClosest(255,255,255); # find white $im->transparent($white); binmode STDOUT; print $im->png; =back =head2 Special Colors GD implements a number of special colors that can be used to achieve special effects. They are constants defined in the GD:: namespace, but automatically exported into your namespace when the GD module is loaded. =over 4 =item B<$image-EsetBrush($image)> You can draw lines and shapes using a brush pattern. Brushes are just palette, not TrueColor, images that you can create and manipulate in the usual way. When you draw with them, their contents are used for the color and shape of the lines. To make a brushed line, you must create or load the brush first, then assign it to the image using setBrush(). You can then draw in that with that brush using the B special color. It's often useful to set the background of the brush to transparent so that the non-colored parts don't overwrite other parts of your image. Example: # Create a brush at an angle $diagonal_brush = GD::Image->new(5,5); $white = $diagonal_brush->colorAllocate(255,255,255); $black = $diagonal_brush->colorAllocate(0,0,0); $diagonal_brush->transparent($white); $diagonal_brush->line(0,4,4,0,$black); # NE diagonal # Set the brush $myImage->setBrush($diagonal_brush); # Draw a circle using the brush $myImage->arc(50,50,25,25,0,360,gdBrushed); =item B<$image-EsetThickness($thickness)> Lines drawn with line(), rectangle(), arc(), and so forth are 1 pixel thick by default. Call setThickness() to change the line drawing width. =item B<$image-EsetStyle(@colors)> Styled lines consist of an arbitrary series of repeated colors and are useful for generating dotted and dashed lines. To create a styled line, use setStyle() to specify a repeating series of colors. It accepts an array consisting of one or more color indexes. Then draw using the B special color. Another special color, B can be used to introduce holes in the line, as the example shows. Example: # Set a style consisting of 4 pixels of yellow, # 4 pixels of blue, and a 2 pixel gap $myImage->setStyle($yellow,$yellow,$yellow,$yellow, $blue,$blue,$blue,$blue, gdTransparent,gdTransparent); $myImage->arc(50,50,25,25,0,360,gdStyled); To combine the C and C behaviors, you can specify C. In this case, a pixel from the current brush pattern is rendered wherever the color specified in setStyle() is neither gdTransparent nor 0. =item B Draw filled shapes and flood fills using a pattern. The pattern is just another image. The image will be tiled multiple times in order to fill the required space, creating wallpaper effects. You must call C in order to define the particular tile pattern you'll use for drawing when you specify the gdTiled color. details. =item B The gdStyled color is used for creating dashed and dotted lines. A styled line can contain any series of colors and is created using the setStyled() command. =item B The C color is used for drawing lines with antialiasing turned on. Antialiasing will blend the jagged edges of lines with the background, creating a smoother look. The actual color drawn is set with setAntiAliased(). =item B<$image-EsetAntiAliased($color)> "Antialiasing" is a process by which jagged edges associated with line drawing can be reduced by blending the foreground color with an appropriate percentage of the background, depending on how much of the pixel in question is actually within the boundaries of the line being drawn. All line-drawing methods, such as line() and polygon, will draw antialiased lines if the special "color" B is used when calling them. setAntiAliased() is used to specify the actual foreground color to be used when drawing antialiased lines. You may set any color to be the foreground, however as of libgd version 2.0.12 an alpha channel component is not supported. Antialiased lines can be drawn on both truecolor and palette-based images. However, attempts to draw antialiased lines on highly complex palette-based backgrounds may not give satisfactory results, due to the limited number of colors available in the palette. Antialiased line-drawing on simple backgrounds should work well with palette-based images; otherwise create or fetch a truecolor image instead. When using palette-based images, be sure to allocate a broad spectrum of colors in order to have sufficient colors for the antialiasing to use. =item B<$image-EsetAntiAliasedDontBlend($color,[$flag])> Normally, when drawing lines with the special B "color," blending with the background to reduce jagged edges is the desired behavior. However, when it is desired that lines not be blended with one particular color when it is encountered in the background, the setAntiAliasedDontBlend() method can be used to indicate the special color that the foreground should stand out more clearly against. Once turned on, you can turn this feature off by calling setAntiAliasedDontBlend() with a second argument of 0: $image->setAntiAliasedDontBlend($color,0); =back =head2 Drawing Commands These methods allow you to draw lines, rectangles, and ellipses, as well as to perform various special operations like flood-fill. =over 4 =item B<$image-EsetPixel($x,$y,$color)> This sets the pixel at (x,y) to the specified color index. No value is returned from this method. The coordinate system starts at the upper left at (0,0) and gets larger as you go down and to the right. You can use a real color, or one of the special colors gdBrushed, gdStyled and gdStyledBrushed can be specified. Example: # This assumes $peach already allocated $myImage->setPixel(50,50,$peach); =item B<$image-Eline($x1,$y1,$x2,$y2,$color)> This draws a line from (x1,y1) to (x2,y2) of the specified color. You can use a real color, or one of the special colors gdBrushed, gdStyled and gdStyledBrushed. Example: # Draw a diagonal line using the currently defined # paintbrush pattern. $myImage->line(0,0,150,150,gdBrushed); =item B<$image-EdashedLine($x1,$y1,$x2,$y2,$color)> DEPRECATED: The libgd library provides this method solely for backward compatibility with libgd version 1.0, and there have been reports that it no longer works as expected. Please use the setStyle() and gdStyled methods as described below. This draws a dashed line from (x1,y1) to (x2,y2) in the specified color. A more powerful way to generate arbitrary dashed and dotted lines is to use the setStyle() method described below and to draw with the special color gdStyled. Example: $myImage->dashedLine(0,0,150,150,$blue); =item B<$image-Erectangle($x1,$y1,$x2,$y2,$color)> This draws a rectangle with the specified color. (x1,y1) and (x2,y2) are the upper left and lower right corners respectively. Both real color indexes and the special colors gdBrushed, gdStyled and gdStyledBrushed are accepted. Example: $myImage->rectangle(10,10,100,100,$rose); =item B<$image-EfilledRectangle($x1,$y1,$x2,$y2,$color)> =item B<$image-EsetTile($otherimage)> This draws a rectangle filled with the specified color. You can use a real color, or the special fill color gdTiled to fill the polygon with a pattern. Example: # read in a fill pattern and set it $tile = GD::Image->newFromPng('happyface.png'); $myImage->setTile($tile); # draw the rectangle, filling it with the pattern $myImage->filledRectangle(10,10,150,200,gdTiled); =item B<$image-EopenPolygon($polygon,$color)> This draws a polygon with the specified color. The polygon must be created first (see below). The polygon must have at least three vertices. If the last vertex doesn't close the polygon, the method will close it for you. Both real color indexes and the special colors gdBrushed, gdStyled and gdStyledBrushed can be specified. Example: $poly = GD::Polygon->new; $poly->addPt(50,0); $poly->addPt(99,99); $poly->addPt(0,99); $myImage->openPolygon($poly,$blue); =item B<$image-EunclosedPolygon($polygon,$color)> This draws a sequence of connected lines with the specified color, without connecting the first and last point to a closed polygon. The polygon must be created first (see below). The polygon must have at least three vertices. Both real color indexes and the special colors gdBrushed, gdStyled and gdStyledBrushed can be specified. You need libgd 2.0.33 or higher to use this feature. Example: $poly = GD::Polygon->new; $poly->addPt(50,0); $poly->addPt(99,99); $poly->addPt(0,99); $myImage->unclosedPolygon($poly,$blue); =item B<$image-EfilledPolygon($poly,$color)> This draws a polygon filled with the specified color. You can use a real color, or the special fill color gdTiled to fill the polygon with a pattern. Example: # make a polygon $poly = GD::Polygon->new; $poly->addPt(50,0); $poly->addPt(99,99); $poly->addPt(0,99); # draw the polygon, filling it with a color $myImage->filledPolygon($poly,$peachpuff); =item B<$image-Eellipse($cx,$cy,$width,$height,$color)> =item B<$image-EfilledEllipse($cx,$cy,$width,$height,$color)> These methods() draw ellipses. ($cx,$cy) is the center of the arc, and ($width,$height) specify the ellipse width and height, respectively. filledEllipse() is like Ellipse() except that the former produces filled versions of the ellipse. =item B<$image-Earc($cx,$cy,$width,$height,$start,$end,$color)> This draws arcs and ellipses. (cx,cy) are the center of the arc, and (width,height) specify the width and height, respectively. The portion of the ellipse covered by the arc are controlled by start and end, both of which are given in degrees from 0 to 360. Zero is at the right end of the ellipse, and angles increase clockwise. To specify a complete ellipse, use 0 and 360 as the starting and ending angles. To draw a circle, use the same value for width and height. You can specify a normal color or one of the special colors B, B, or B. Example: # draw a semicircle centered at 100,100 $myImage->arc(100,100,50,50,0,180,$blue); =item B<$image-EfilledArc($cx,$cy,$width,$height,$start,$end,$color [,$arc_style])> This method is like arc() except that it colors in the pie wedge with the selected color. $arc_style is optional. If present it is a bitwise OR of the following constants: gdArc connect start & end points of arc with a rounded edge gdChord connect start & end points of arc with a straight line gdPie synonym for gdChord gdNoFill outline the arc or chord gdEdged connect beginning and ending of the arc to the center gdArc and gdChord are mutually exclusive. gdChord just connects the starting and ending angles with a straight line, while gdArc produces a rounded edge. gdPie is a synonym for gdArc. gdNoFill indicates that the arc or chord should be outlined, not filled. gdEdged, used together with gdNoFill, indicates that the beginning and ending angles should be connected to the center; this is a good way to outline (rather than fill) a "pie slice." Example: $image->filledArc(100,100,50,50,0,90,$blue,gdEdged|gdNoFill); =item B<$image-Efill($x,$y,$color)> This method flood-fills regions with the specified color. The color will spread through the image, starting at point (x,y), until it is stopped by a pixel of a different color from the starting pixel (this is similar to the "paintbucket" in many popular drawing toys). You can specify a normal color, or the special color gdTiled, to flood-fill with patterns. Example: # Draw a rectangle, and then make its interior blue $myImage->rectangle(10,10,100,100,$black); $myImage->fill(50,50,$blue); =item B<$image-EfillToBorder($x,$y,$bordercolor,$color)> Like C, this method flood-fills regions with the specified color, starting at position (x,y). However, instead of stopping when it hits a pixel of a different color than the starting pixel, flooding will only stop when it hits the color specified by bordercolor. You must specify a normal indexed color for the bordercolor. However, you are free to use the gdTiled color for the fill. Example: # This has the same effect as the previous example $myImage->rectangle(10,10,100,100,$black); $myImage->fillToBorder(50,50,$black,$blue); =back =head2 Image Copying Commands Two methods are provided for copying a rectangular region from one image to another. One method copies a region without resizing it. The other allows you to stretch the region during the copy operation. With either of these methods it is important to know that the routines will attempt to flesh out the destination image's color table to match the colors that are being copied from the source. If the destination's color table is already full, then the routines will attempt to find the best match, with varying results. =over 4 =item B<$image-Ecopy($sourceImage,$dstX,$dstY,$srcX,$srcY,$width,$height)> This is the simplest of the several copy operations, copying the specified region from the source image to the destination image (the one performing the method call). (srcX,srcY) specify the upper left corner of a rectangle in the source image, and (width,height) give the width and height of the region to copy. (dstX,dstY) control where in the destination image to stamp the copy. You can use the same image for both the source and the destination, but the source and destination regions must not overlap or strange things will happen. Example: $myImage = GD::Image->new(100,100); ... various drawing stuff ... $srcImage = GD::Image->new(50,50); ... more drawing stuff ... # copy a 25x25 pixel region from $srcImage to # the rectangle starting at (10,10) in $myImage $myImage->copy($srcImage,10,10,0,0,25,25); =item B<$image-Eclone()> Make a copy of the image and return it as a new object. The new image will look identical. However, it may differ in the size of the color palette and other nonessential details. Example: $myImage = GD::Image->new(100,100); ... various drawing stuff ... $copy = $myImage->clone; =item B<$image-EcopyMerge($sourceImage,$dstX,$dstY,> B< $srcX,$srcY,$width,$height,$percent)> This copies the indicated rectangle from the source image to the destination image, merging the colors to the extent specified by percent (an integer between 0 and 100). Specifying 100% has the same effect as copy() -- replacing the destination pixels with the source image. This is most useful for highlighting an area by merging in a solid rectangle. Example: $myImage = GD::Image->new(100,100); ... various drawing stuff ... $redImage = GD::Image->new(50,50); ... more drawing stuff ... # copy a 25x25 pixel region from $srcImage to # the rectangle starting at (10,10) in $myImage, merging 50% $myImage->copyMerge($srcImage,10,10,0,0,25,25,50); =item B<$image-EcopyMergeGray($sourceImage,$dstX,$dstY,> B< $srcX,$srcY,$width,$height,$percent)> This is identical to copyMerge() except that it preserves the hue of the source by converting all the pixels of the destination rectangle to grayscale before merging. =item B<$image-EcopyResized($sourceImage,$dstX,$dstY,> B< $srcX,$srcY,$destW,$destH,$srcW,$srcH)> This method is similar to copy() but allows you to choose different sizes for the source and destination rectangles. The source and destination rectangle's are specified independently by (srcW,srcH) and (destW,destH) respectively. copyResized() will stretch or shrink the image to accommodate the size requirements. Example: $myImage = GD::Image->new(100,100); ... various drawing stuff ... $srcImage = GD::Image->new(50,50); ... more drawing stuff ... # copy a 25x25 pixel region from $srcImage to # a larger rectangle starting at (10,10) in $myImage $myImage->copyResized($srcImage,10,10,0,0,50,50,25,25); =item B<$image-EcopyResampled($sourceImage,$dstX,$dstY,> B< $srcX,$srcY,$destW,$destH,$srcW,$srcH)> This method is similar to copyResized() but provides "smooth" copying from a large image to a smaller one, using a weighted average of the pixels of the source area rather than selecting one representative pixel. This method is identical to copyResized() when the destination image is a palette image. =item B<$image-EcopyRotated($sourceImage,$dstX,$dstY,> B< $srcX,$srcY,$width,$height,$angle)> Like copyResized() but the $angle argument specifies an arbitrary amount to rotate the image counter clockwise (in degrees). In addition, $dstX and $dstY species the B
of the destination image, and not the top left corner. =item B<$image-EtrueColorToPalette([$dither], [$colors])> This method converts a truecolor image to a palette image. The code for this function was originally drawn from the Independent JPEG Group library code, which is excellent. The code has been modified to preserve as much alpha channel information as possible in the resulting palette, in addition to preserving colors as well as possible. This does not work as well as might be hoped. It is usually best to simply produce a truecolor output image instead, which guarantees the highest output quality. Both the dithering (0/1, default=0) and maximum number of colors used (<=256, default = gdMaxColors) can be specified. =item B<$image = $sourceImage-EcreatePaletteFromTrueColor([$dither], [$colors])> Creates a new palette image from a truecolor image. Same as above, but returns a new image. Don't use these function -- write real truecolor PNGs and JPEGs. The disk space gain of conversion to palette is not great (for small images it can be negative) and the quality loss is ugly. =item B<$error = $image-EcolorMatch($otherimage)> Bring the palette colors in $otherimage to be closer to truecolor $image. A negative return value is a failure. -1 image must be True Color -2 otherimage must be indexed -3 the images are meant to be the same dimensions -4 At least 1 color in otherimage must be allocated This method is only available with libgd >= 2.1.0 =item B<$image = $sourceImage-EneuQuant($maxcolor=256,$samplefactor=5)> Creates a new palette image from a truecolor image. =over 4 =item samplefactor The quantization precision between 1 (highest quality) and 10 (fastest). =item maxcolor The number of desired palette entries. =back This is the same as createPaletteFromTrueColor with the quantization method GD_QUANT_NEUQUANT. This does not support dithering. This method is only available with libgd >= 2.1.0 =back =head2 Image Transformation Commands Gd provides these simple image transformations, non-interpolated. =over 4 =item B<$image = $sourceImage-EcopyRotate90()> =item B<$image = $sourceImage-EcopyRotate180()> =item B<$image = $sourceImage-EcopyRotate270()> =item B<$image = $sourceImage-EcopyFlipHorizontal()> =item B<$image = $sourceImage-EcopyFlipVertical()> =item B<$image = $sourceImage-EcopyTranspose()> =item B<$image = $sourceImage-EcopyReverseTranspose()> These methods can be used to rotate, flip, or transpose an image. The result of the method is a copy of the image. =item B<$image-Erotate180()> =item B<$image-EflipHorizontal()> =item B<$image-EflipVertical()> These methods are similar to the copy* versions, but instead modify the image in place. =back =head2 Image Interpolation Methods Since libgd 2.1.0 there are better transformation methods, with these interpolation methods: GD_BELL - Bell GD_BESSEL - Bessel GD_BILINEAR_FIXED - fixed point bilinear GD_BICUBIC - Bicubic GD_BICUBIC_FIXED - fixed point bicubic integer GD_BLACKMAN - Blackman GD_BOX - Box GD_BSPLINE - BSpline GD_CATMULLROM - Catmullrom GD_GAUSSIAN - Gaussian GD_GENERALIZED_CUBIC - Generalized cubic GD_HERMITE - Hermite GD_HAMMING - Hamming GD_HANNING - Hannig GD_MITCHELL - Mitchell GD_NEAREST_NEIGHBOUR - Nearest neighbour interpolation GD_POWER - Power GD_QUADRATIC - Quadratic GD_SINC - Sinc GD_TRIANGLE - Triangle GD_WEIGHTED4 - 4 pixels weighted bilinear interpolation GD_LINEAR - bilinear interpolation =over 4 =item B<$image-EinterpolationMethod( [$method] )> Gets or sets the interpolation methods for all subsequent interpolations. See above for the valid values. Only available since libgd 2.2.0 =item B<$image-EcopyScaleInterpolated( width, height )> Returns a copy, using interpolation. =item B<$image-EcopyRotateInterpolated( angle, bgcolor )> Returns a copy, using interpolation. =back =head2 Image Filter Commands Gd also provides some common image filters, they modify the image in place and return TRUE if modified or FALSE if not. Most of them need libgd >= 2.1.0, with older versions those functions are undefined. =over 4 =item B<$ok = $image-Escatter($sub, $plus)> if $sub and $plus are 0, nothing is changed, TRUE is returned. if $sub >= $plus, nothing is changed, FALSE is returned. else random pixels are changed. =item B<$ok = $image-EscatterColor($sub, $plus, @colors)> Similar to scatter, but using the given array of colors, i.e. palette indices. =item B<$ok = $image-Epixelate($blocksize, $mode)> if $blocksize <= 0, nothing is changed, FALSE is returned. if $blocksize == 1, nothing is changed, TRUE is returned. else the following modes are observed: GD_PIXELATE_UPPERLEFT GD_PIXELATE_AVERAGE =item B<$ok = $image-Enegate()> =item B<$ok = $image-Egrayscale()> =item B<$ok = $image-Ebrightness($add)> $add: -255..255 =item B<$ok = $image-Econtrast($contrast)> $contrast: a double value. The contrast adjustment value. Negative values increase, positive values decrease the contrast. The larger the absolute value, the stronger the effect. =item B<$ok = $image-Ecolor($red,$green,$blue,$alpha)> Change channel values of an image. $red - The value to add to the red channel of all pixels. $green - The value to add to the green channel of all pixels. $blue - The value to add to the blue channel of all pixels. $alpha - The value to add to the alpha channel of all pixels. =item B<$ok = $image-EselectiveBlur()> =item B<$ok = $image-EedgeDetectQuick()> =item B<$ok = $image-EgaussianBlur()> =item B<$ok = $image-Eemboss()> =item B<$ok = $image-EmeanRemoval()> =item B<$ok = $image-Esmooth($weight)> =item B<$image = $sourceImage-EcopyGaussianBlurred($radius, $sigma)> $radius: int, the blur radius (*not* diameter--range is 2*radius + 1) a radius, not a diameter so a radius of 2 (for example) will blur across a region 5 pixels across (2 to the center, 1 for the center itself and another 2 to the other edge). $sigma: the sigma value or a value <= 0.0 to use the computed default. represents the "fatness" of the curve (lower == fatter). The result is always truecolor. =back =head2 Character and String Drawing GD allows you to draw characters and strings, either in normal horizontal orientation or rotated 90 degrees. These routines use a GD::Font object, described in more detail below. There are four built-in monospaced fonts, available in the global variables B, B, B, B and B. In addition, you can use the load() method to load GD-formatted bitmap font files at runtime. You can create these bitmap files from X11 BDF-format files using the bdf2gd.pl script, which should have been installed with GD (see the bdf_scripts directory if it wasn't). The format happens to be identical to the old-style MSDOS bitmap ".fnt" files, so you can use one of those directly if you happen to have one. For writing proportional scalable fonts, GD offers the stringFT() method, which allows you to load and render any TrueType font on your system. =over 4 =item B<$image-Estring($font,$x,$y,$string,$color)> This method draws a string starting at position (x,y) in the specified font and color. Your choices of fonts are gdSmallFont, gdMediumBoldFont, gdTinyFont, gdLargeFont and gdGiantFont. Example: $myImage->string(gdSmallFont,2,10,"Peachy Keen",$peach); =item B<$image-EstringUp($font,$x,$y,$string,$color)> Just like the previous call, but draws the text rotated counterclockwise 90 degrees. =item B<$image-Echar($font,$x,$y,$char,$color)> =item B<$image-EcharUp($font,$x,$y,$char,$color)> These methods draw single characters at position (x,y) in the specified font and color. They're carry-overs from the C interface, where there is a distinction between characters and strings. Perl is insensible to such subtle distinctions. =item $font = Bload($fontfilepath)> This method dynamically loads a font file, returning a font that you can use in subsequent calls to drawing methods. For example: my $courier = GD::Font->load('./courierR12.fnt') or die "Can't load font"; $image->string($courier,2,10,"Peachy Keen",$peach); Font files must be in GD binary format, as described above. =item B<@bounds = $image-EstringFT($fgcolor,$fontname,$ptsize,$angle,$x,$y,$string)> =item B<@bounds = GD::Image-EstringFT($fgcolor,$fontname,$ptsize,$angle,$x,$y,$string)> =item B<@bounds = $image-EstringFT($fgcolor,$fontname,$ptsize,$angle,$x,$y,$string,\%options)> This method uses TrueType to draw a scaled, antialiased string using the TrueType vector font of your choice. It requires that libgd to have been compiled with TrueType support, and for the appropriate TrueType font to be installed on your system. The arguments are as follows: fgcolor Color index to draw the string in fontname A path to the TrueType (.ttf) font file or a font pattern. ptsize The desired point size (may be fractional) angle The rotation angle, in radians (positive values rotate counter clockwise) x,y X and Y coordinates to start drawing the string string The string itself If successful, the method returns an eight-element list giving the boundaries of the rendered string: @bounds[0,1] Lower left corner (x,y) @bounds[2,3] Lower right corner (x,y) @bounds[4,5] Upper right corner (x,y) @bounds[6,7] Upper left corner (x,y) In case of an error (such as the font not being available, or FT support not being available), the method returns an empty list and sets $@ to the error message. The B argument is the name of the font, which can be a full pathname to a F<.ttf> file, or if not the paths in C<$ENV{GDFONTPATH}> will be searched or if empty the libgd compiled DEFAULT_FONTPATH. The TrueType extensions .ttf, .pfa, .pfb or .dfont can be omitted. The string may contain UTF-8 sequences like: "À" You may also call this method from the GD::Image class name, in which case it doesn't do any actual drawing, but returns the bounding box using an inexpensive operation. You can use this to perform layout operations prior to drawing. Using a negative color index will disable antialiasing, as described in the libgd manual page at L. An optional 8th argument allows you to pass a hashref of options to stringFT(). Several hashkeys are recognized: B, B, B, and B. The value of B is supposed to be a multiple of the character height, so setting linespacing to 2.0 will result in double-spaced lines of text. However the current version of libgd (2.0.12) does not do this. Instead the linespacing seems to be double what is provided in this argument. So use a spacing of 0.5 to get separation of exactly one line of text. In practice, a spacing of 0.6 seems to give nice results. Another thing to watch out for is that successive lines of text should be separated by the "\r\n" characters, not just "\n". The value of B is one of "Unicode", "Shift_JIS" and "Big5". The interaction between Perl, Unicode and libgd is not clear to me, and you should experiment a bit if you want to use this feature. The value of B is the vertical and horizontal resolution, in DPI, in the format "hdpi,vdpi". If present, the resolution will be passed to the Freetype rendering engine as a hint to improve the appearance of the rendered font. The value of B is a flag. Set it to false to turn off the default kerning of text. Example: $gd->stringFT($black,'/c/windows/Fonts/pala.ttf',40,0,20,90, "hi there\r\nbye now", {linespacing=>0.6, charmap => 'Unicode', }); If GD was compiled with fontconfig support, and the fontconfig library is available on your system, then you can use a font name pattern instead of a path. Patterns are described in L and will look something like this "Times:italic". For backward compatibility, this feature is disabled by default. You must enable it by calling useFontConfig(1) prior to the stringFT() call. $image->useFontConfig(1); For backward compatibility with older versions of the FreeType library, the alias stringTTF() is also recognized. =item B<$hasfontconfig = $image-EuseFontConfig($flag)> Call useFontConfig() with a value of 1 in order to enable support for fontconfig font patterns (see stringFT). Regardless of the value of $flag, this method will return a true value if the fontconfig library is present, or false otherwise. This method can also be called as a class method of GD::Image; =item B<$result = $image-EstringFTCircle($cx,$cy,$radius,$textRadius,$fillPortion,$font,$points,$top,$bottom,$fgcolor)> This draws text in a circle. Currently (libgd 2.0.33) this function does not work for me, but the interface is provided for completeness. The call signature is somewhat complex. Here is an excerpt from the libgd manual page: Draws the text strings specified by top and bottom on the image, curved along the edge of a circle of radius radius, with its center at cx and cy. top is written clockwise along the top; bottom is written counterclockwise along the bottom. textRadius determines the "height" of each character; if textRadius is 1/2 of radius, characters extend halfway from the edge to the center. fillPortion varies from 0 to 1.0, with useful values from about 0.4 to 0.9, and determines how much of the 180 degrees of arc assigned to each section of text is actually occupied by text; 0.9 looks better than 1.0 which is rather crowded. font is a freetype font; see gdImageStringFT. points is passed to the freetype engine and has an effect on hinting; although the size of the text is determined by radius, textRadius, and fillPortion, you should pass a point size that "hints" appropriately -- if you know the text will be large, pass a large point size such as 24.0 to get the best results. fgcolor can be any color, and may have an alpha component, do blending, etc. Returns a true value on success. =back =head2 Alpha channels The alpha channel methods allow you to control the way drawings are processed according to the alpha channel. When true color is turned on, colors are encoded as four bytes, in which the last three bytes are the RGB color values, and the first byte is the alpha channel. Therefore the hexadecimal representation of a non transparent RGB color will be: C=0x00(rr)(bb)(bb) When alpha blending is turned on, you can use the first byte of the color to control the transparency, meaning that a rectangle painted with color 0x00(rr)(bb)(bb) will be opaque, and another one painted with 0x7f(rr)(gg)(bb) will be transparent. The Alpha value must be >= 0 and <= 0x7f. =over 4 =item B<$image-EalphaBlending($integer)> The alphaBlending() method allows for two different modes of drawing on truecolor images. In blending mode, which is on by default (libgd 2.0.2 and above), the alpha channel component of the color supplied to all drawing functions, such as C, determines how much of the underlying color should be allowed to shine through. As a result, GD automatically blends the existing color at that point with the drawing color, and stores the result in the image. The resulting pixel is opaque. In non-blending mode, the drawing color is copied literally with its alpha channel information, replacing the destination pixel. Blending mode is not available when drawing on palette images. Pass a value of 1 for blending mode, and 0 for non-blending mode. =item B<$image-EsaveAlpha($saveAlpha)> By default, GD (libgd 2.0.2 and above) does not attempt to save full alpha channel information (as opposed to single-color transparency) when saving PNG images. (PNG is currently the only output format supported by gd which can accommodate alpha channel information.) This saves space in the output file. If you wish to create an image with alpha channel information for use with tools that support it, call C to turn on saving of such information, and call C to turn off alpha blending within the library so that alpha channel information is actually stored in the image rather than being composited immediately at the time that drawing functions are invoked. =back =head2 Miscellaneous Image Methods These are various utility methods that are useful in some circumstances. =over 4 =item B<$image-Einterlaced([$flag])> This method sets or queries the image's interlaced setting. Interlace produces a cool venetian blinds effect on certain viewers. Provide a true parameter to set the interlace attribute. Provide undef to disable it. Call the method without parameters to find out the current setting. =item B<($width,$height) = $image-EgetBounds()> This method will return a two-member list containing the width and height of the image. You query but not change the size of the image once it's created. =item B<$width = $image-Ewidth> =item B<$height = $image-Eheight> Return the width and height of the image, respectively. =item B<$is_truecolor = $image-EisTrueColor()> This method will return a Boolean representing whether the image is true color or not. =item B<$flag = $image1-Ecompare($image2)> Compare two images and return a bitmap describing the differences found, if any. The return value must be logically AND'ed with one or more constants in order to determine the differences. The following constants are available: GD_CMP_IMAGE The two images look different GD_CMP_NUM_COLORS The two images have different numbers of colors GD_CMP_COLOR The two images' palettes differ GD_CMP_SIZE_X The two images differ in the horizontal dimension GD_CMP_SIZE_Y The two images differ in the vertical dimension GD_CMP_TRANSPARENT The two images have different transparency GD_CMP_BACKGROUND The two images have different background colors GD_CMP_INTERLACE The two images differ in their interlace GD_CMP_TRUECOLOR The two images are not both true color The most important of these is GD_CMP_IMAGE, which will tell you whether the two images will look different, ignoring differences in the order of colors in the color palette and other invisible changes. The constants are not imported by default, but must be imported individually or by importing the :cmp tag. Example: use GD qw(:DEFAULT :cmp); # get $image1 from somewhere # get $image2 from somewhere if ($image1->compare($image2) & GD_CMP_IMAGE) { warn "images differ!"; } =item B<$image-Eclip($x1,$y1,$x2,$y2)> =item B<($x1,$y1,$x2,$y2) = $image-Eclip> Set or get the clipping rectangle. When the clipping rectangle is set, all drawing will be clipped to occur within this rectangle. The clipping rectangle is initially set to be equal to the boundaries of the whole image. Change it by calling clip() with the coordinates of the new clipping rectangle. Calling clip() without any arguments will return the current clipping rectangle. =item B<$flag = $image-EboundsSafe($x,$y)> The boundsSafe() method will return true if the point indicated by ($x,$y) is within the clipping rectangle, or false if it is not. If the clipping rectangle has not been set, then it will return true if the point lies within the image boundaries. =back =head2 Grouping Methods GD does not support grouping of objects, but GD::SVG does. In that subclass, the following methods declare new groups of graphical objects: =over 4 =item $image-EstartGroup([$id,\%style]) =item $image-EendGroup() =item $group = $image-EnewGroup See L for information. =back =head1 Polygons A few primitive polygon creation and manipulation methods are provided. They aren't part of the Gd library, but I thought they might be handy to have around (they're borrowed from my qd.pl Quickdraw library). Also see L. =over 3 =item B<$poly = GD::Polygon-Enew> Create an empty polygon with no vertices. $poly = GD::Polygon->new; =item B<$poly-EaddPt($x,$y)> Add point (x,y) to the polygon. $poly->addPt(0,0); $poly->addPt(0,50); $poly->addPt(25,25); $myImage->fillPoly($poly,$blue); =item B<($x,$y) = $poly-EgetPt($index)> Retrieve the point at the specified vertex. ($x,$y) = $poly->getPt(2); =item B<$poly-EsetPt($index,$x,$y)> Change the value of an already existing vertex. It is an error to set a vertex that isn't already defined. $poly->setPt(2,100,100); =item B<($x,$y) = $poly-EdeletePt($index)> Delete the specified vertex, returning its value. ($x,$y) = $poly->deletePt(1); =item B<$poly-Eclear()> Delete all vertices, restoring the polygon to its initial empty state. =item B<$poly-EtoPt($dx,$dy)> Draw from current vertex to a new vertex, using relative (dx,dy) coordinates. If this is the first point, act like addPt(). $poly->addPt(0,0); $poly->toPt(0,50); $poly->toPt(25,-25); $myImage->fillPoly($poly,$blue); =item B<$vertex_count = $poly-Elength> Return the number of vertices in the polygon. $points = $poly->length; =item B<@vertices = $poly-Evertices> Return a list of all the vertices in the polygon object. Each member of the list is a reference to an (x,y) array. @vertices = $poly->vertices; foreach $v (@vertices) print join(",",@$v),"\n"; } =item B<@rect = $poly-Ebounds> Return the smallest rectangle that completely encloses the polygon. The return value is an array containing the (left,top,right,bottom) of the rectangle. ($left,$top,$right,$bottom) = $poly->bounds; =item B<$poly-Eoffset($dx,$dy)> Offset all the vertices of the polygon by the specified horizontal (dh) and vertical (dy) amounts. Positive numbers move the polygon down and to the right. $poly->offset(10,30); =item B<$poly-Erotate($rad)> Rotate all the vertices of the polygon by the specified clockwise radian angle. use Math::Trig; $poly->rotate(deg2rad(180)); =item B<$poly-Emap($srcL,$srcT,$srcR,$srcB,$destL,$dstT,$dstR,$dstB)> Map the polygon from a source rectangle to an equivalent position in a destination rectangle, moving it and resizing it as necessary. See polys.pl for an example of how this works. Both the source and destination rectangles are given in (left,top,right,bottom) coordinates. For convenience, you can use the polygon's own bounding box as the source rectangle. # Make the polygon really tall $poly->map($poly->bounds,0,0,50,200); =item B<$poly-Escale($sx,[$sy, [$tx,$ty]])> Scale each vertex of the polygon by the X and Y factors indicated by sx and sy. For example scale(2,2) will make the polygon twice as large. For best results, move the center of the polygon to position (0,0) before you scale, then move it back to its previous position. Accepts an optional offset vector. Undefined $sy defaults to $sx, ie. scale(2.0) scales the polyon by 2. =item B<$poly-Etransform($sx,$sy, $rx,$ry, $tx,$ty)> Run each vertex of the polygon through a 2D affine transformation matrix, where sx and sy are the X and Y scaling factors, rx and ry are the X and Y rotation factors, and tx and ty are X and Y offsets.

For more fonts, compile libgd with TrueType support and use the stringFT() call. If you wish to add more built-in fonts, the directory bdf_scripts contains two contributed utilities that may help you convert X-Windows BDF-format fonts into the format that libgd uses internally. However these scripts were written for earlier versions of GD which included its own mini-gd library. These scripts will have to be adapted for use with libgd, and the libgd library itself will have to be recompiled and linked! Please do not contact me for help with these scripts: they are unsupported. Each of these fonts is available both as an imported global (e.g. B) and as a package method (e.g. BSmall>). =over 5 =item B =item BSmall> This is the basic small font, "borrowed" from a well known public domain 6x12 font. =item B =item BLarge> This is the basic large font, "borrowed" from a well known public domain 8x16 font. =item B =item BMediumBold> This is a bold font intermediate in size between the small and large fonts, borrowed from a public domain 7x13 font; =item B =item BTiny> This is a tiny, almost unreadable font, 5x8 pixels wide. =item B =item BGiant> This is a 9x15 bold font converted by Jan Pazdziora from a sans serif X11 font. =item B<$font-Enchars> This returns the number of characters in the font. print "The large font contains ",gdLargeFont->nchars," characters\n"; =item B<$font-Eoffset> This returns the ASCII value of the first character in the font =item B<$width = $font-Ewidth> =item B<$height = $font-Eheight> =item C These return the width and height of the font.

It also adds a small number of "turtle graphics" style calls for those who prefer to work in polar coordinates. In addition, the library allows you to use symbolic names for colors, such as "chartreuse", and will manage the colors for you. =head2 The Pen GD::Simple maintains a "pen" whose settings are used for line- and shape-drawing operations. The pen has the following properties: =over 4 =item fgcolor The pen foreground color is the color of lines and the borders of filled and unfilled shapes. =item bgcolor The pen background color is the color of the contents of filled shapes. =item pensize The pen size is the width of the pen. Larger sizes draw thicker lines. =item position The pen position is its current position on the canvas in (X,Y) coordinates. =item angle When drawing in turtle mode, the pen angle determines the current direction of lines of relative length. =item turn When drawing in turtle mode, the turn determines the clockwise or counterclockwise angle that the pen will turn before drawing the next line. =item font The font to use when drawing text. Both built-in bitmapped fonts and TrueType fonts are supported. =item fontsize The size of the font to use when drawing with TrueType fonts. =back One sets the position and properties of the pen and then draws. As the drawing progresses, the position of the pen is updated. =head2 Methods GD::Simple introduces a number of new methods, a few of which have the same name as GD::Image methods, and hence change their behavior. In addition to these new methods, GD::Simple objects support all of the GD::Image methods. If you make a method call that isn't directly supported by GD::Simple, it refers the request to the underlying GD::Image object. Hence one can load a JPEG image into GD::Simple and declare it to be TrueColor by using this call, which is effectively inherited from GD::Image: my $img = GD::Simple->newFromJpeg('./myimage.jpg',1); The rest of this section describes GD::Simple-specific methods. =cut use strict; use GD; use GD::Group; use Math::Trig; use Carp 'croak'; our @ISA = 'Exporter'; our @EXPORT = @GD::EXPORT; our

The pen is moved to the end of the drawn string. Depending on the font selected with the font() method, this will use either a bitmapped GD font or a TrueType font. The angle of the pen will be consulted when drawing the text. For TrueType fonts, any angle is accepted. For GD bitmapped fonts, the angle can be either 0 (draw horizontal) or -90 (draw upwards). For consistency between the TrueType and GD font behavior, the string is always drawn so that the current position of the pen corresponds to the bottom left of the first character of the text. This is different from the GD behavior, in which the first character of bitmapped fonts hangs down from the pen point. This method returns a polygon indicating the bounding box of the rendered text.

It can be invoked as an instance method (on a previously-created GD::Simple object) or as a class method (on the 'GD::Simple' class). When called as an instance method, fontMetrics() takes no arguments and returns a single hash reference containing the metrics that describe the currently selected font and size. The hash reference contains the following information: xheight the base height of the font from the bottom to the top of a lowercase 'm' ascent the length of the upper stem of the lowercase 'd' descent the length of the lower step of the lowercase 'j' lineheight the distance from the bottom of the 'j' to the top of the 'd' leading the distance between two adjacent lines This description and code was changed with 2.75. =cut # return %$fontmetrics # keys: 'ascent', 'descent', 'lineheight', 'xheight', 'leading' sub fontMetrics { my $self = shift; unless (ref $self) { #class invocation -- create a scratch $self = $self->new; $self->font(shift) if defined $_[0]; $self->fontsize(shift) if defined $_[0]; } my $font = $self->font; my $metrics; if (ref $font && $font->isa('GD::Font')) { my $height = $font->height; $metrics = {ascent => 0, descent => 0, lineheight => $height, xheight => $height, leading => 0}; } else { $self->useFontConfig(1); my @mbounds = GD::Image->stringFT($self->fgcolor,$font, $self->fontsize,0, 0,0,'m'); my $xheight = $mbounds[3]-$mbounds[5]; my @jbounds = GD::Image->stringFT($self->fgcolor,$font, $self->fontsize,0, 0,0,'j'); my $ascent = $mbounds[7]-$jbounds[7]; my $descent = $jbounds[3]-$mbounds[3]; my @mmbounds = GD::Image->stringFT($self->fgcolor,$font, $self->fontsize,0, 0,0,"m\nm"); my $twolines = $mmbounds[3]-$mmbounds[5]; my $lineheight = $twolines - 2*$xheight; my $leading = $lineheight - $ascent - $descent; $metrics = {ascent => $ascent, descent => $descent, lineheight => $lineheight, xheight => $xheight, leading => $leading}; } if ((my $string = shift) && wantarray) { my ($width,$height) = $self->stringBounds($string); return ($metrics,abs($width),abs($height)); } return $metrics; } =item ($delta_x,$delta_y)= $img->stringBounds($string) This method indicates the X and Y offsets (which may be negative) that will occur when the given string is drawn using the current font, fontsize and angle.

This is only valid for TrueType fonts. =cut sub fontsize { my $self = shift; $self->{fontsize} = shift if @_; $self->{fontsize}; } =item $size = $img->penSize([$newpensize]) Get or set the current pen width for use during line drawing operations. =cut sub penSize { my $self = shift; if (@_) { $self->{pensize} = shift; $self->gd->setThickness($self->{pensize}); } $self->{pensize}; } =item $angle = $img->angle([$newangle]) Set the current angle for use when calling line() or move() with a single argument. Here is an example of using turn() and angle() together to draw an octagon. The first line drawn is the downward-slanting top right edge. The last line drawn is the horizontal top of the octagon. $img->moveTo(200,50); $img->angle(0); $img->turn(360/8); for (1..8) { $img->line(50) } =cut sub angle { my $self = shift; $self->{angle} = shift if @_; $self->{angle}; } =item $angle = $img->turn([$newangle]) Get or set the current angle to turn prior to drawing lines. This value is only used when calling line() or move() with a single argument. The turning angle will be applied to each call to line() or move() just before the actual drawing occurs. Angles are in degrees. Positive values turn the angle clockwise. =cut # degrees, not radians sub turn { my $self = shift; $self->{turningangle} = shift if @_; $self->{turningangle}; } =item $color = $img->fgcolor([$newcolor]) Get or set the pen's foreground color.

The list of color names can be obtained using color_names(). The special color name 'transparent' will create a completely transparent color. =cut sub fgcolor { my $self = shift; $self->{fgcolor} = $self->translate_color(@_) if @_; $self->{fgcolor}; } =item $color = $img->bgcolor([$newcolor]) Get or set the pen's background color.

Think of a polyline as "an open polygon", that is, the last vertex is not connected to the first vertex (unless you expressly add the same value as both points). For the remainder of this doc, "polyline" will refer to a GD::Polyline, "polygon" will refer to a GD::Polygon that is not a polyline, and "polything" and "$poly" may be either. The big feature added to GD by this module is the means to create splines, which are approximations to curves. =head1 The Polyline Object GD::Polyline defines the following class: =over 5 =item C A polyline object, used for storing lists of vertices prior to rendering a polyline into an image. =item C Cnew> I Create an empty polyline with no vertices. $polyline = GD::Polyline->new; $polyline->addPt( 0, 0); $polyline->addPt( 0,100); $polyline->addPt( 50,100); $polyline->addPt(100, 0); $image->polydraw($polyline,$black); In fact GD::Polyline is a subclass of GD::Polygon, so all polygon methods (such as B and B) may be used on polylines. Some new methods have thus been added to GD::Polygon (such as B) and a few updated/modified/enhanced (such as B) I. See section "New or Updated GD::Polygon Methods" for more info. =back Note that this module is very "young" and should be considered subject to change in future releases, and/or possibly folded in to the existing polygon object and/or GD module. =head1 Updated Polygon Methods The following methods (defined in GD.pm) are OVERRIDDEN if you use this module. All effort has been made to provide 100% backward compatibility, but if you can confirm that has not been achieved, please consider that a bug and let the the author of Polyline.pm know. =over 5 =item C C<$poly-Escale($sx, $sy, $cx, $cy)> I Scale a polything in along x-axis by $sx and along the y-axis by $sy, about centery point ($cx, $cy). Center point ($cx, $cy) is optional -- if these are omitted, the function will scale about the origin. To flip a polything, use a scale factor of -1. For example, to flip the polything top to bottom about line y = 100, use: $poly->scale(1, -1, 0, 100); =back =head1 New Polygon Methods The following methods are added to GD::Polygon, and thus can be used by polygons and polylines. Don't forget: a polyline is a GD::Polygon, so GD::Polygon methods like offset() can be used, and they can be used in GD::Image methods like filledPolygon(). =over 5 =item C C<$poly-Erotate($angle, $cx, $cy)> I Rotate a polything through $angle (clockwise, in radians) about center point ($cx, $cy). Center point ($cx, $cy) is optional -- if these are omitted, the function will rotate about the origin In this function and other angle-oriented functions in GD::Polyline, positive $angle corresponds to clockwise rotation. This is opposite of the usual Cartesian sense, but that is because the raster is opposite of the usual Cartesian sense in that the y-axis goes "down". =item C C<($cx, $cy) = $poly-Ecentroid($scale)> I Calculate and return ($cx, $cy), the centroid of the vertices of the polything. For example, to rotate something 180 degrees about it's centroid: $poly->rotate(3.14159, $poly->centroid()); $scale is optional; if supplied, $cx and $cy are multiplied by $scale before returning. The main use of this is to shift an polything to the origin like this: $poly->offset($poly->centroid(-1)); =item C C<@segLengths = $poly-EsegLength()> I In array context, returns an array the lengths of the segments in the polything. Segment n is the segment from vertex n to vertex n+1. Polygons have as many segments as vertices; polylines have one fewer. In a scalar context, returns the sum of the array that would have been returned in the array context. =item C C<@segAngles = $poly-EsegAngle()> I Returns an array the angles of each segment from the x-axis. Segment n is the segment from vertex n to vertex n+1. Polygons have as many segments as vertices; polylines have one fewer. Returned angles will be on the interval 0 <= $angle < 2 * pi and angles increase in a clockwise direction. =item C C<@vertexAngles = $poly-EvertexAngle()> I Returns an array of the angles between the segment into and out of each vertex. For polylines, the vertex angle at vertex 0 and the last vertex are not defined; however $vertexAngle[0] will be undef so that $vertexAngle[1] will correspond to vertex 1. Returned angles will be on the interval 0 <= $angle < 2 * pi and angles increase in a clockwise direction. Note that this calculation does not attempt to figure out the "interior" angle with respect to "inside" or "outside" the polygon, but rather, just the angle between the adjacent segments in a clockwise sense. Thus a polygon with all right angles will have vertex angles of either pi/2 or 3*pi/2, depending on the way the polygon was "wound". =item C C<$poly-EtoSpline()> I Create a new polything which is a reasonably smooth curve using cubic spline algorithms, often referred to as Bezier curves. The "source" polything is called the "control polything". If it is a polyline, the control polyline must have 4, 7, 10, or some number of vertices of equal to 3n+1. If it is a polygon, the control polygon must have 3, 6, 9, or some number of vertices of equal to 3n. $spline = $poly->toSpline(); $image->polydraw($spline,$red); In brief, groups of four points from the control polyline are considered "control points" for a given portion of the spline: the first and fourth are "anchor points", and the spline passes through them; the second and third are "director points". The spline does not pass through director points, however the spline is tangent to the line segment from anchor point to adjacent director point. The next portion of the spline reuses the previous portion's last anchor point. The spline will have a cusp (non-continuous slope) at an anchor point, unless the anchor points and its adjacent director point are colinear. In the current implementation, toSpline() return a fixed number of segments in the returned polyline per set-of-four control points. In the future, this and other parameters of the algorithm may be configurable. =item C C<$polyline-EaddControlPoints()> I So you say: "OK. Splines sound cool. But how can I get my anchor points and its adjacent director point to be colinear so that I have a nice smooth curves from my polyline?" Relax! For The Lazy: addControlPoints() to the rescue. addControlPoints() returns a polyline that can serve as the control polyline for toSpline(), which returns another polyline which is the spline. Is your head spinning yet? Think of it this way: =over 5 =item + If you have a polyline, and you have already put your control points where you want them, call toSpline() directly. Remember, only every third vertex will be "on" the spline. You get something that looks like the spline "inscribed" inside the control polyline. =item + If you have a polyline, and you want all of its vertices on the resulting spline, call addControlPoints() and then toSpline(): $control = $polyline->addControlPoints(); $spline = $control->toSpline(); $image->polyline($spline,$red); You get something that looks like the control polyline "inscribed" inside the spline. =back Adding "good" control points is subjective; this particular algorithm reveals its author's tastes. In the future, you may be able to alter the taste slightly via parameters to the algorithm. For The Hubristic: please build a better one! And for The Impatient: note that addControlPoints() returns a polyline, so you can pile up the call like this, if you'd like: $image->polyline($polyline->addControlPoints()->toSpline(),$mauve); =back =head1 New GD::Image Methods =over 5 =item C C<$image-Epolyline(polyline,color)> I $image->polyline($polyline,$black) This draws a polyline with the specified color. Both real color indexes and the special colors gdBrushed, gdStyled and gdStyledBrushed can be specified. Neither the polyline() method or the polygon() method are very picky: you can call either method with either a GD::Polygon or a GD::Polyline. The I determines if the shape is "closed" or "open" as drawn, I the object type. =item C C<$image-Epolydraw(polything,color)> I $image->polydraw($poly,$black) This method draws the polything as expected (polygons are closed, polylines are open) by simply checking the object type and calling either $image->polygon() or $image->polyline(). =back =head1 Examples Please see file "polyline-examples.pl" that is included with the distribution. =head1 See Also For more info on Bezier splines, see http://www.webreference.com/dlab/9902/bezier.html. =head1 Future Features On the drawing board are additional features such as: - polygon winding algorithms (to determine if a point is "inside" or "outside" the polygon) - new polygon from bounding box - find bounding polygon (tightest fitting simple convex polygon for a given set of vertices) - addPts() method to add many points at once - clone() method for polygon - functions to interwork GD with SVG Please provide input on other possible features you'd like to see. =head1 Author This module has been written by Daniel J.

There are a number of ways to obtain BDF fonts. =over 4 =item 1. The font is already present on your system. Some BDF fonts can be found in the standard X11R6 distribution. This script will automatically uncompress gzipped font files if their extension ends with .gz (the gunzip program must be on your path). =item 2. From a font server. The "fstobdf" utility, a standard X11 utility, will read a named font from the font server of your choice and return it in BDF format. You can pipe it to bdf2gdfont.pl: fstobdf -s fontserverhost:7100 -fn 8x16 | bdf2gdfont.pl > newfont.fnt Use xlsfonts to find out what fonts are available. Most fonts will have long names like -B&H-LucidaTypewriter-Bold-R-Normal-Sans-18-180-75-75-M-110-ISO8859-10. =item 3. Using the pcf2bdf utility. Some fonts are only available in PCF (compiled) format. To obtain these, you can either turn on a font server and follow recipe (2), or use TAGA Nayuta's pcf2bdf utility. This utility is available from http://www.tsg.ne.jp/GANA/S/pcf2bdf/ (page is in Japanese, but you can find the download link). =back =head2 Limitations This font converter only works with fixed-width fonts. If used with a TrueType or proportional font it will die with an error message. =head1 SEE ALSO L =head1 AUTHOR Lincoln Stein , heavily adapted from bdftogd from Jan Pazdziora .

Some monospaced fonts may still not work. Test # with "bdftogd" before running this script if you are unsure. # 4) copy "bdftogd" and "cvtbdf.pl" to the "fonts" directory # 5) run "cvtbdf.pl" # 6) go to your GD.pm source installation directory and install the new # version via a "make" and "make install" # # Notes - # A) Keep the "fonts" subdirectory and all fonts you wish to use in the # future. Each time you want to add a font you will need the old ones # in the directory, or they will disappear during the next recompile. # B) Add new fonts in the future is as easy as copying the .bdf file to # the "fonts" directory and running steps #5 and #6 again. # # Thanks - # To Lincoln Stein for the use of CGI.pm and GD.pm and to all other # contributors of those packages. # make sure we have the conversion program if (! -x "bdftogd") { die "OOPS!\n Can't execute 'bdftogd', is it even there?\n error: $!\n\n"; } &badnames; &saveorig("GD.pm","GD.xs","libgd/Makefile.PL"); ©orig("GD.pm","GD.xs","libgd/Makefile.PL"); for $i (@files) { open(OLDXS,"../GD.xs") || die "OOPS!\n Can't open '../GD.xs' for reading\n Make sure you're in a 'fonts' subdirectory\n error: $!\n\n"; open(NEWXS,"> ../GD.xs.fonts") || die "OOPS!\n Can't open '../GD.xs.fonts' for writing\n Make sure you're in a 'fonts' subdirectory\n error: $!\n\n"; open(OLDPM,"../GD.pm") || die "OOPS!\n Can't open '../GD.pm' for reading\n Make sure you're in a 'fonts' subdirectory\n error: $!\n\n"; open(NEWPM,"> ../GD.pm.fonts") || die "OOPS!\n Can't open '../GD.pm.fonts' for writing\n Make sure you're in a 'fonts' subdirectory\n error: $!\n\n"; open(OLDMAKE,"../libgd/Makefile.PL") || die "OOPS!\n Can't open '../libgd/Makefile.PL' for reading\n Make sure you're in a 'fonts' subdirectory\n error: $!\n\n"; open(NEWMAKE,"> ../libgd/Makefile.PL.fonts") || die "OOPS!\n Can't open '../libgd/Makefile.PL.fonts' for writing\n Make sure you're in a 'fonts' subdirectory\n error: $!\n\n"; # some state-keeping variables my $extern; my $package; my $export; my $preload; my $h; my $c; # figure out our "name" my $name = "BDF" . $i; $name =~ /(.*)\.bdf/; $name = $1; print "=> name = $name\n"; # do the actual font conversion: open(FONT,"$i"); # usage: bdftogd fontname filename, eg. bdftogd FontLarge gdfontl } my $fontname = "Font" . $name; my $filename = "font" . $name; my $gdname = "gdfont" . $name; open(CONVERT,"| bdftogd $fontname $filename"); while () { print CONVERT; } close CONVERT; # move the font files to "../libgd" open(OLD,"${gdname}.h"); open(NEW,"> ../libgd/${gdname}.h"); while () { print NEW; } close OLD; close NEW; unlink("${gdname}.h"); open(OLD,"${gdname}.c"); open(NEW,"> ../libgd/${gdname}.c"); while () { print NEW; } close OLD; close NEW; unlink("${gdname}.c"); ## Begin editing files # GD.xs: while () { $data = $_; if (! $extern && $data =~ /^extern[\s]{1,}gdFontPtr/) { $data = "extern gdFontPtr gdFont" . $name .
