What is a PGM image?
PGM (Portable Gray Map) files store grayscale 2D images. Each pixel within the image contains only one or two bytes of information (8 or 16 bits). While that might not sound like a lot of information, PGM files can hold tens of thousands of shades — ranging from pure black to white, and every shade of gray in between.
How do I view PGM files?
Since PGM files are saved in plain text, you can also open them with a text editor, such as Microsoft Notepad or Apple TextEdit, or a source code editor. You may need to rename the . pgm file extension to . txt for the text editor to recognize it.
