The G4 file extension is linked to the CCITT Group 4 Fax Image format, recognized by the International Telecommunication Union (ITU) for its ability to compress monochrome images without data loss. This format is integral to fax technology, employing a two-dimensional coding system that identifies image patterns, resulting in high compression ratios and minimized file sizes, key for efficient document transmission.
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.
