The RLE (Run-Length Encoded) file extension, associated with the Utah Raster Toolkit, is a lossless image compression format used primarily for 4 or 8-bit bitmap images. Developed at the University of Utah, it employs run-length encoding to compress data by reducing consecutive repeated values, making it efficient for simple graphics like icons and line drawings. Historically, it was widely used in early versions of Windows and CompuServe software.
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.
