This is a bitmap image format that is built into the ImageMagick software library. It is used in customizable templates that support the ability to change gradients. These templates produce unique images with vivid and rich transitions when applied to images.

Was developed for the first mass-produced e-book reader – Rocket eBook. The format is written in Ruby. RB files are containers holding the entire content for a Rocket eBook device. It has DRM protection capability which is not used in the books published at present due to the format’s lack of popularity.
