LibGD - GD library

LibGD

What is the GD library?
GD is an open source code library for the dynamic creation of images by programmers. GD creates PNG, JPEG and GIF images, among other formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly. While not restricted to use on the web, the most common applications of GD involve web site development.
GD is written in C and various binding are available. See a non exaustive list here .
The library was originally developped by Thomas Boutell and is now maintained by Pierre-A. Joye under the umbrella of PHP.net.
