Define image toolkits provided by this module.

The file which includes each toolkit's functions must be declared as part of the files array in the module .info file so that the registry will find and parse it.

The toolkit's functions must be named image_toolkitname_operation(). where the operation may be:

• 'load': Required. See image_gd_load() for usage.
• 'save': Required. See image_gd_save() for usage.
• 'settings': Optional. See image_gd_settings() for usage.
• 'resize': Optional. See image_gd_resize() for usage.
• 'rotate': Optional. See image_gd_rotate() for usage.
• 'crop': Optional. See image_gd_crop() for usage.
• 'desaturate': Optional. See image_gd_desaturate() for usage.

Return value

An array with the toolkit name as keys and sub-arrays with these keys:

• 'title': A string with the toolkit's title.
• 'available': A Boolean value to indicate that the toolkit is operating properly, e.g. all required libraries exist.
