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 and other

|
|
|
languages. GD can read and write many different image formats. GD is commonly
|
|
|
|
|
used to generate charts, graphics, thumbnails, and most anything else, on the
|
|
|
|
|
fly.

The most common applications of GD involve website development, although it
|
|
|
|
|
can be used with any standalone application!

|
The library was originally developed by Thomas Boutell and is now maintained

by many contributors (see the [CONTRIBUTORS](CONTRIBUTORS) file) under the

|
|
umbrella of PHP.net.
