Silicon Graphics Image (.sgi)

The Silicon Graphics Image (SGI) file format, developed by Silicon Graphics Inc. in 1995, is a raster graphics format designed for high-quality color images. It supports 8 to 32 bits per pixel, three primary color channels, and an optional alpha channel for transparency. The format employs run-length encoding (RLE) compression to minimize file sizes. Initially utilized on Silicon Graphics workstations, the SGI format remains compatible with modern image viewers and editors.

Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
