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.

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.
