Sun Raster (often `.ras` or `.sun`) is the native bitmap format for the SunOS and Solaris operating systems developed by Sun Microsystems. It was the standard format for icons, wallpapers, and screen captures on Sun workstations (SPARCstations) during the 1990s.
It is a simple format consisting of a fixed-length header (32 bytes) followed by an optional color map and the image data. The data can be uncompressed or RLE compressed. It supports standard depths: 1-bit (bitmap), 8-bit (indexed), 24-bit (truecolor), and 32-bit (truecolor + alpha, though alpha support was inconsistent).
Ubiquitous in the Unix workstation era when Sun Microsystems dominated the enterprise and academic markets. It faded into obscurity alongside the decline of Solaris and the rise of PNG.
