Convert PPM to UBRL6

The Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.

The UBRL6 file extension, short for Unicode Braille 6 Dots, is a text encoding format that uses a 6-dot braille cell to represent characters, symbols, and punctuation marks. It enables the conversion of text into a tactile code system, facilitating reading for individuals with visual impairments. UBRL6 supports both uncontracted and contracted braille fonts and leverages Unicode to cover a wide range of characters from different writing systems. This format is particularly useful for developers and organizations working on accessibility solutions.
