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.; VIPS is a libvips file format mainly used for calculations, but it can also store images. The main advantage is that it has no size limit; it's fast and straightforward. Nonetheless, most applications can't view it, so converting it to a more popular format is the only way to work around it.
