Convert TXT COMMONMARKX to PPM

The TXT file extension, which represents CommonMark Markdown Language with Extensions is a standardized, plain-text formatting syntax designed to be converted to HTML. CommonMark aims to improve the readability and portability of text, and it is widely used in documentation, forums, and note-taking applications. Extensions enhance its functionality, such as adding support for annotations, form inputs, and other 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.
