Image API, Image GD, ImageMagick Drupal modules description

This API interface is intended as a replacement for the image APIs provided by image.inc. You do not need to install this module unless another module requires it. It does not add new features to your Drupal site — it only provides an API that other modules can use. Currently, GD2 and ImageMagick are supported and bundled with ImageAPI.

Note: Requires PHP5!

Differences from Drupal core’s image.inc:

1. Images are handled as objects.
2. Images are not saved after every operation; they must be explicitly saved after processing is complete.
3. Multiple image toolkits can be used simultaneously. However, ImageAPI opens the image using only one toolkit, and further processing is handled within that same toolkit.
