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 HRZ file extension is integral to Slow Scan Television (SSTV), a digital imaging technique used in amateur radio to transmit images via radio waves. The HRZ format efficiently stores images in a 256 x 240 RGB bitmap, making it ideal for low-bandwidth transmissions. SSTV encodes images into audio signals, which are then decoded back into visual files, producing an HRZ file. This technology is crucial for image communication in bandwidth-constrained environments.
