Convert CAL to ISOBRL6

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 ISOBRL6 file extension, short for ISO/TR 11548-1 Braille 6 dots, is a digital format used to store and represent Braille characters and documents. It is an enhanced version of the original ISOBRL format, offering improved features for displaying textual and symbolic information in Braille. This format supports a wide range of Braille codes, character sets, and languages, making it suitable for Braille printing, displays, and electronic readers for visually impaired individuals. The ISOBRL6 format adheres to the international standard ISO/IEC 14496-28, ensuring compact and portable representation of Braille text for electronic systems.
