About PGM (.PGM)
PGM stands for Portable Gray Map, a simple grayscale image file format. It is widely used for storing grayscale images in a straightforward, uncompressed manner that makes it easy to read and edit.
Technical Details
A PGM file stores pixel values as plain text or binary data representing shades from black to white. It starts with a header specifying the format type, image width, height, and maximum gray value, followed by the pixel data. This simplicity makes PGM ideal for testing and educational purposes in image processing.
Additional Information & Use Cases
PGM files are part of the Netpbm format family, which also includes PBM (bitmap) and PPM (color image) files. These formats were developed in the 1980s to provide a simple way to exchange images between different platforms and image processing tools.
