Eyefi ImageModifier 0.4

Eyefi ImageModifier library is a high-level programming interface for describing and caching a series of image transformations which are applied to source images, typically for display on web pages.
The work process is as follows: you define a chain of transformations, optionally giving it a name, and then apply an image to this chain, which results in a new image. If the image is applied to the chain a second time, a cached image will be used.
Currently, the following filters are defined:
- resize
- border
- apply color mask
- round corners
- cropping (to ratio, to dimension, square)
- color blending
- text (ttf / t1)
- margin
- overlay (for watermarking)
- grayscale
The sub-pages of this project document these different filters, the general ImageModifier API, and integration with the Smarty template engine.
Enhancements:
- A new source mask modifier which can draw masked text over images, and several other minor features and bugfixes.
