Sun Raster was a raster graphics file format used on SunOS by Sun Microsystems . [1] The format has no MIME type, [2] it is specified in @(#)rasterfile.h 1.11 89/08/21 SMI . The format was used for some research papers. [3] [4]

ACDSee , FFmpeg , GIMP , ImageMagick , IrfanView , LibreOffice , Netpbm , PaintShop Pro , PMView , and XnView among others support Sun Raster image files. [5] [6] In version 2.13 XnView supported the file extensions .ras and .sun for this graphics file format . In version 2.1.4 FFmpeg could encode and decode Sun Raster pixel formats bgr24, pal8, gray, and monow. [7] The format does not support transparency.

The plain text Sun icon format specified in @(#)icon_load.h 10.5 89/09/05 SMI is unrelated to the Sun Raster format. [8]
