GD is an open source code library for the dynamic creation of images by programmers.
GD is written in C, and “wrappers” are available for Perl, PHP, ruby and many other bindings. It can create GIFs, JPEGs, PNGs, and WBMPs.
GD can create images composed of lines, arcs, text (using program-selected fonts), other images, and multiple colors. Version 2.0 adds support for truecolor images, alpha channels, resampling (for smooth resizing of truecolor images), and many other features.
GD supports numerous programming languages including C, PHP, Perl, Python, OCaml, Tcl, Lua, Pascal, GNU Octave, REXX, Ruby and Go. Additional, the “Fly” command line interpreter allows for image creation (“on the fly”) using GD. GD scripts can thus be written in potentially any language and run using this tool.
This is free and open source software.
