After more than a year of development, I released version 1.0 of ChunkyPNG, the pure Ruby library for handling PNG images, and OilyPNG, the C module that will speed it up.

The new ChunkyPNG release comes packed with new features: image resizing, polygon and circle drawing methods, more efficient image operations like rotate and flip, a simplified API and better documentation, etc.; see the changelog for all the changes. OilyPNG now comes with a C implementation of image composition, which significantly speeds up the generation of sprite images.

As always, use gem install {chunky,oily}_png to install. Feedback is welcome!
