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 CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
