Convert CALS to TXT BRAILLE6DOTS

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.

A TXT file extension, associated with "Unicode Braille 6 Dots", refers to the representation of braille characters within the Unicode standard, specifically using a 6-dot cell configuration. This allows for the encoding of braille patterns, making it accessible for visually impaired users to read and write text digitally. The history of braille dates back to its invention by Louis Braille in the 19th century, and its inclusion in Unicode ensures compatibility across various digital platforms.
