Convert TXT CREOLE to PNM

The TXT file extension represents Creole Markup Language (CML), which is a lightweight markup language designed to standardize wiki syntax, facilitating content transfer between different wiki engines. Conceived during the 2006 International Symposium on Wikis, Creole amalgamates common elements from major wiki engines, with MediaWiki's syntax often used as a fallback. Released as version 1.0 on July 4, 2007, Creole is supported by various wiki platforms, including Bitbucket wikis and Moodle. It simplifies content creation and editing across diverse wiki environments.

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.
