Drupal有很多很强大的模块，Imagecache就是一个强大的图片编辑模块，可以对图片就行缩放、剪裁等简单操作。而ImageCache Action在Imagecache的基础上，提供了更为强大的操作。
ImageCache Actions的图片编辑功能有：
- 添加水印：Watermarking – a much requested addition that enables you to place any image anywhere over a source picture, with alpha transparency
- 图片叠加：Overlays – Add photo-corners etc to the image
- 加添文字：Text overlay – add a short copyright notice to your image, using available system fonts
- 颜色变换：Color-shifting – Colorize images. Also invert.
- 亮度调整：Brighten/Darken
- 通道便捷：Alpha blending – turn an image into a transparent mask, and back into a flat image against another color

- 画布操作：Canvas manipulation – add padding, either onto color or transparent backgrounds
- 背景图片：Background – Place your image onto another source background
- 图片文件格式转换：File Format switcher – If you need tranparency in JPGs : make them PNG. If your PNG thumbnails are 30K each, save them as JPGs
- 图片圆角实现：Rounded corners (transparent). With input from canaryMason, we can even set different radius for different corners, and round just one corner etc.
- 调整长宽比：Aspect Switcher new 2009-08 – lets you perform different actions or use different dimensions based on whether the image is ‘landscape’ or ‘portrait’
- 自定义操作：Custom Actions – Execute your own PHP/GD code in the middle of an imagecache generation process. Requires some familiarity with imageAPI internals.
