Convert PBM to UBRL

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.

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.
