GD is written in C, and "wrappers" are available for Perl, PHP and other
|
|
Packit |
ed3af9 |
languages. GD can read and write many different image formats. GD is commonly
|
|
Packit |
ed3af9 |
used to generate charts, graphics, thumbnails, and most anything else, on the
|
|
Packit |
ed3af9 |
fly.

The most common applications of GD involve website development, although it
|
|
Packit |
ed3af9 |
can be used with any standalone application!

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