- Description
- The CALS Raster Graphic File, having the extension .cals, is a type of image file format primarily used for the storage and exchange of digital images, especially in the context of technical and engineering documents. Developed in the mid-1980s by the United States Department of Defense, the CALS format was part of an initiative to standardize electronic document management and interchange, particularly for military and government applications.
- Image file format related to the .PNG format, but uses lossy compression like standard .JPG files; developed as a sub-format for .MNG objects, but can also be used as a standalone raster image format.
