g1nn13 fork changes: * added buffer() method to get image buffer for writing (to Amazon S3) * added fit_within() method to resize an image to fit within a specified height and width without changing the image's aspect ratio * added resize_with_crop() to resize and crop images where the target aspect ratio differs from the original aspect ratio. This is for converting portrait to landscape and landscape to portrait. ImageScience is a clean and happy Ruby library that generates thumbnails -- and kicks the living crap out of RMagick. Oh, and it doesn't leak memory like a sieve. :) For more information including build steps, see http://seattlerb.rubyforge.org/
