Convert PPM to ISOBRL

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 ISOBRL file extension is associated with ISO/TR 11548-1 Braille, a standard for encoding 8-dot Braille characters. It is used to store textual documents in a digital format, making it accessible for blind or visually impaired individuals. This standard, established by the International Organization for Standardization (ISO), ensures compatibility across various Braille input and output devices. The ISOBRL format facilitates the exchange of Braille documents in a consistent and standardized manner.
