Convert XML JATS to PNM

The Journal Article Tag Suite (JATS) XML file extension is pivotal in digital publishing. XML stands for Extensible Markup Language. JATS, an NISO standard, was designed to tag and structure the content of scholarly articles. Initially derived from NLM (National Library of Medicine) DTDs in the early 2000s, JATS ensures consistent formatting and metadata tagging for articles, facilitating efficient indexing, searchability, and interoperability across various databases and platforms. Its use in the academic and scientific community supports robust archiving and seamless dissemination of knowledge.

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.
