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 While it was useful in the past, the ART format has largely been replaced by more modern image formats.

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.
