What is the .RAS File Extension?
.RAS File Extension Description:
The RAS file extension belongs to the image file category and is described as a SUN Raster Image File, developed by Sun Microsystems. Originally, the .ras image format was introduced under the UNIX platform using Sub Microsystems applications; but it was later re-created to conform to other platforms, like Microsoft Windows, Linux, Macintosh, and so on.
The .ras file extension supports 1 to 32 bits per pixel in rasterizing images for different image authoring applications. The image file may be released in compressed or uncompressed form depending on the software used to create the image. RLE is the common compression method used in .ras images.
A raster image is composed of a rectangular array of sample values, or pixels, and each is associated with corresponding numbers that specify a color for that certain pixel. Regular .ras image files in 24-bits total have color values ranging from 0 to 255, which define the amount of red, green, and blue colors per pixel.
Values for red, green, and blue can be combined to produce black, white, a total of 254 shades of grey, and so on. Considering the number of bits present in a .ras image, a total of 16,777,216 color combinations can be created by mixing color values per pixel.
Unlike other image files, the RAS format is, oftentimes, uncompressed, which results in large file size compared to compressed image files, like JPG, PNG, GIF, and so on. Also, the .ras file format has no text support capability included in its structure; it is just a combination of colored pixels formed to create an image, whether the output resembles an image or text.Author: Sun Microsystems
