# SGI

## Overview

GIMP can both read and write to the SGI file format. This format, by Silicon Graphics Inc., supports black and white (usually with the extension `.bw`), color (`.rgb`), and color images with an alpha channel (`.rgba`). You may also find SGI files in any of the above formats with the extension `.sgi`. SGI images are normally only found on SGI workstations.

## SGI Options

When saving an SGI image, GIMP will prompt you to specify a compression type. RLE (Run Length Encoded) compression is recommended because it is a lossless format. The Aggressive RLE option may produce a smaller file size, but SGI applications may not open the image correctly.
