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 (.sun)

The Sun Raster (SUN) file extension, originating from Sun Microsystems, is a bitmap image format used primarily on SunOS systems. Known for its versatility in storing raster graphics, it supports various color depths, from monochrome to 24-bit true color. Initially created for the Sun workstation's image processing software, it facilitated efficient graphical data manipulation and transmission. Over time, its straightforward structure and compatibility with different Unix-based systems ensured its adoption in diverse graphic applications. Today, while largely historical, the SUN file format remains an important part of the legacy of early computer graphics development.
