"It's like a Swiss Army Knife for images, but one of those tiny ones you can
keep on your keychain" AND YES, it works with Rails!
SmartImage is an image processing/compositing/thumbnailing Ruby with the
following design goals:
- Completely seamless installation and usage across all Ruby
implementations, with an emphasis on MRI and JRuby
- Expose a small but powerful and easy-to-understand API
- Easy to extend with support for multiple image compositing backends
(presently RMagick and Java Graphics2D)
That's cool, so what can it do?
- Create thumbnails (even in your Ruby on Rails application!)
- Scale images
- Composite multiple images into a single image
- Convert between various image formats (.png, .jpg, and .gif presently
supported)
- Apply alpha masks to an image
Why should I use SmartImage instead of RMagick, ImageScience, etc?
- You want a more powerful and more cross-platform library than
ImageScience
- You want a library with a less mind-bogglingly bloated API than RMagick
- You're considering a move to an alternative Ruby implementation like
JRuby and want an image library that works seamlessly between MRI, JRuby,
and other Ruby implementations

v0.0.4 release notes:
- Fixed bug in processing alpha channel of JRuby canvas objects when
saving .jpgs, causing color channel corruption.
- Fixed bug in SmartImage.thumbnail_file where images are always saved as
.pngs regardless of the specified file extension.
