Convert CALS to BRF

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.

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.
