The latest version of the library is 9.09.04, released on September 4, 2009.

There are three packages available for download: full (contains the library, unit tests, documentation, and demos), lib (contains only the library), and doc (contains API documentation).

Download

• Download from SourceForge.net
  You can select the package that best suits your needs:
  • lib – the library
  • full – the library, API documentation, unit tests, demos
  • doc – API documentation only
• SVN tag 9.09.04

Requirements

• PHP 5.2 or higher (may work on lower, but no guarantees and support for it)
• GD2 extension
• No special settings are required, but you should pay attention to memory_limit and max_execution_time php.ini directives, because image operations can take up a lot of time and memory. For example, just loading a 1920×1200 true-color image takes up about 1920 * 1200 * 4 bytes + overhead ~= 9 MB of memory.
