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.
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.
