Convert TEXT MARKDOWN to PPM

A TEXT file extension, associated with Markdown Documentation, which simplifies writing and formatting text for web and technical documentation. Markdown, created by John Gruber in 2004, facilitates easy-to-read, plain-text documents that can be converted to HTML. It's essential for developers and writers to create structured documents quickly and efficiently, enhancing productivity and readability without complex code.

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.
