Convert WIKI TIKIWIKI to PPM

The TikiWiki Markup Language (WIKI), is a markup language used in Tiki Wiki CMS Groupware to format and present content on wiki pages. It simplifies text formatting by using common characters in unique ways, eliminating the need for HTML knowledge. Introduced to enhance user-friendliness, TikiWiki supports various text formatting options like bold, italic, and underlined text, as well as headings, lists, and tables. Its development has evolved alongside Tiki Wiki CMS, incorporating features like syntax highlighting and plugins for advanced functionalities.

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.
