Convert CAL to BRF

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 Braille Ready Format (BRF) is a digital text file format used to store braille transcriptions. Developed by the National Federation of the Blind and the American Printing House for the Blind, BRF files represent braille pages in ASCII text, making them readable by braille displays and embossers. This format supports both contracted and uncontracted braille, facilitating accessibility for visually impaired users. BRF files are essential for converting printed text into a format usable by braille notetakers and refreshable braille displays.
