A .ras extension file is a binary raster image format file that was developed using the UNIX platform by Sun Microsystems. It uses the bitmap format that is simple to use and has the ability to store data in grayscale, black and white as well as colored pixels. The basic layout of a .ras file begins with a header, is followed by a color map and finally by the image data that is bitmapped.
