محول XCF إلى RB مجاني عبر الإنترنت

This is a file format for storing projects in the GIMP image editor. It supports the storage of vector and bitmap graphics, layers, guides, selections, and channels that are saved in an XCF project in a compressed form but without loss of quality. It is the analogue of PSD for the Photoshop software.

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.
