Sun Microsystems, a technology company that was active from 1982 to 2010, created the Sun Raster Graphic format for use on its SunOS workstations and servers. Sun Raster Graphics can contain raw or compressed image data, with image depths (bits per pixel) of 1, 4, 8, 24, or 32 bits.

Some Sun Raster Graphics are saved as RS files. More commonly, Sun Raster Graphics are saved as .SUN or .RAS files. An easy way to identify a Sun Raster Graphic, regardless of its extension, is to view the file's 32-bit header in a hex editor. All Sun Raster Graphics include the identifying magic number 59a66a95 in their header.
