Convert CALS to UBRL

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 UBRL file extension stands for Unicode Braille and is used to represent Braille characters using Unicode encoding. Developed to facilitate the exchange and storage of Braille content digitally, it ensures accessibility for individuals with visual impairments. UBRL files are associated with ImageMagick and support both uncontracted and contracted Braille fonts. This format allows for easy integration of Braille text into various applications and systems.
