Convert PPM to TXT BRAILLE6DOTS

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.

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.
