- Description
- 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.
- A MAT-file holds the variables saved from a MATLAB session: numeric arrays such as matrices and images, text, cell arrays and structs. Files saved with -v7.3 are HDF5 files behind a MATLAB header. Unity and Unreal material files use the .mat extension too, but they are a different format.
