Convert WIKI TWIKI to PPM

The TWiki Markup Language (WIKI) file extension is used for documents created with TWiki, an open-source wiki application designed for collaborative documentation and project management. TWiki allows users to format text, and create headings, lists, and tables using simple markup syntax, making it accessible even for those without HTML knowledge. TWiki was developed in the early 2000s and has since been widely adopted for its ease of use and powerful collaboration features.

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.
