As a Bitmap file, PPM adopts a text format to store information about a particular image. Within a PPM file, every pixel has a specific number (from 0 to 65536) and information about the height and width of an image, plus any whitespace data. Therefore, it is always used for basic color image storage and image information exchange.

📌How to open a PPM file?
