RPBM to SGI Conversion: FAQ

What are RPBM files?

The RPBM format is part of a group of portable bitmap formats known as Netpbm, together with PBM, PGM and PPM. All formats were designed by Jef Poskanzer with the aim of improving the transferability of bitmap files between different computers and applications. RPBM files contain monochrome images and they are less common than PBMs, so opening them with currently available image viewers might pose some difficulties.

SGI (Silicon Graphics Image) is a raster image format associated with Silicon Graphics workstations. It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels.
