Convert MARKDOWN to PPM

Markdown is a lightweight markup language with a plain text formatting syntax, primarily used in Markdown documentation files with the MD extension. Created by John Gruber and Aaron Swartz in 2004, it allows IT professionals to easily format text for web pages, readme files, and technical documentation. Markdown's simplicity and readability make it ideal for collaborative projects and version control systems. Its syntax is designed to be readable without compromising the document's formatting when rendered as HTML or other web formats.

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.
