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

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.

AOLpress Raster Technology (.art)

The ART file extension, associated with PFS: 1st Publisher, stands for "AOLpress Raster Technology". Developed by America Online (AOL), this format was designed to optimize image download speeds over slow internet connections by employing high compression ratios. ART files store single, highly compressed images, allowing for incremental rendering similar to progressive JPEGs. While it was useful in the past, the ART format has largely been replaced by more modern image formats.
