Convert TEXT HADDOCK to PNM

The TEXT file extension, associated with Haddock Markup Language, is used for documentation in Haskell programming. Haddock is a tool for generating documentation from annotated Haskell source code. It uses a lightweight markup language, similar to LaTeX, to format the documentation. The history of Haddock dates back to its creation by Simon Marlow and others as part of the GHC (Glasgow Haskell Compiler) project. It has since become a standard tool in the Haskell community for creating comprehensive and readable documentation.

The PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
