A few days ago I released version 0.1 of my Grails ImageTools plugin, based off some work that I’ve done on personal projects. It provides functions for:
- Image loading
- Image saving
- Cropping
- Masking
- Scaling
The latest version of the documentation will remain at the Grails wiki. You probably should also read my post on JAI and masking operations if you intend to use it to mask images.
