Convert CALS to TXT BRAILLE

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 TXT file extension, associated with "Unicode Braille", is primarily used for files with Braille Unicode characters, allowing for the digital representation and accessibility of Braille text for visually impaired individuals. Historically, the use of Unicode Braille in TXT files has evolved to support diverse linguistic characters and symbols, enhancing compatibility across different platforms and devices. This standardization has facilitated broader adoption and improved accessibility in computer technology.
