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.

Sun Raster (.sr)

The Sun Raster (SR) file extension, is a raster graphics file format developed by Sun Microsystems for use on their SunOS operating system. This format, which stores black-and-white, grayscale, and color bitmapped data, was widely used in UNIX-based systems and supported by various imaging applications. The Sun Raster format includes a header, an optional color map, and the bitmapped image data. Although it does not support transparency, it remains a simple and widely distributed bitmap format.
