GD Graphics Library
GD is a graphics library. It allows your code to quickly draw images complete with lines, arcs, text, multiple colours, cut and paste from other images, flood fills, and write out the result as a PNG file. This is particularly useful in World Wide Web applications, where PNG is one of the formats accepted for inline images by most browsers. . This is the runtime package of the library.
