What is the difference between .wdp and .pnm?

Description: Compressed raster image format developed by Microsoft; similar to the .JPG format, but uses a higher degree of compression and supports both lossy and lossless compression; used primarily for high-resolution digital photographs; can be used with several Microsoft products including Windows Photo Viewer, Windows Live Movie Maker (WLMM), and Microsoft Word.; The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
