Convert PNM to PS

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.

The PostScript (PS) file extension stands for "PostScript", a dynamic page description language developed by Adobe in the early 1980s. Primarily used for desktop publishing, vector graphics, and printing tasks, PS files are particularly beneficial in ensuring high-quality output across various devices. As a precursor to PDFs, they encode textual and graphical content with great precision, facilitating consistent rendering on any platform. Renowned for their robust and flexible nature, PostScript files have played a pivotal role in digital typography and printing, underpinning many modern typesetting applications and output systems.
