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, O'Caml, TclTcl (originally from "Tool Command Language", but nonetheless conventionally rendered as "Tcl" rather than "TCL"; and pronounced like "tickle") is a scripting language created by John Ousterhout that is generally thought to be easy to learn, but powerful, PascalPascal is one of the landmark computer programming languages on which generations of students cut their teeth and variants of which are still widely used today. TeX and much of the original Macintosh operating system were written in Pascal. The Swiss comp, and REXXREXX (Restructured Extended Executor) is a programming language which was developed at IBM, and several implementations are available under open source licenses. It is a structured high-level programming language which was designed to be both easy to lear. There is also a tool called fly which allows access to GD from any language through a command-line program.
GD is extensively used with PHP, where a modified version supporting additional features is included by default as of PHP 4.3 and was an option before that.
