Silicon Graphics Image (SGI) or the RGB file format is the native raster graphics file format for Silicon Graphics workstations.[3] The format was invented by Paul Haeberli.[3] It can be run-length encoded (RLE). Among others FFmpeg and ImageMagick support this format.
Background
Common file extensions are:
.sgior.rgb- 3 colour channels
.rgba- 3 colour channels and alpha
.bwor.int- black and white
.inta- black and white and alpha
This format was originally developed for IRIX. The master files of the SVT High Definition Multi Format Test Set are SGIs.[5][6][7] Frame 200 of the ParkJoy sequence in this set (15722.sgi, 3840×2160, 47.4 MB) was used in WebP comparisons.
