Grapher imports and exports Silicon Graphics Image .RGB, .RGBA, and .BW files.
This file format .RGB, .RGBA, .BW originated on Silicon Graphics workstations and is/was used in a variety of high-end imaging applications, both Unix- and Windows-based. The filename extension is sometimes used to indicate the format of the image contained in the file, but is not required to do so. The extensions are typically .BW for black and white images, .RGB for 24-bit color images, and .RGBA for 32-bit color images with an alpha channel.
