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.
The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
