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.
The Sun Raster file extension, also known as RAS, is a bitmap graphics file format developed by Sun Microsystems for use on their SunOS operating system. It supports black-and-white, grayscale, and color images with various pixel depths and includes simple Run-Length Encoding (RLE) compression. The format was widely used in UNIX-based systems and is supported by many imaging applications. The RAS format has largely been superseded by more modern formats but remains relevant for legacy systems and specific use cases.
