Convert WMF to PNM

The Windows Metafile (WMF) is a graphic file format used by Microsoft Windows to store vector and bitmap image data. Originating in the late 1980s, WMF files enable the efficient exchange of graphical content between applications. They serve functions like clip art storage, image rendering in documents, and transferring graphics across different software platforms. Designed to be device-independent, WMF ensures consistent image presentation regardless of the output device, maintaining visual fidelity across varying screen resolutions and printer outputs. As a legacy format, its use has diminished with the advent of more advanced graphical file formats.

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.
