Questions & Answers
RAST files: Frequently Asked Questions
What are RAST files?
RAST is a Sun Raster image format developed for Sun UNIX platforms. These types of operating systems were launched by Sun Microsystems for use on both workstations and server computer systems.

They support various types of image colour depths, from monochrome to 32-bit TrueColor and are mostly designed for UNIX users.
