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.
The JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
