What is a PPM File?
The PPM format stores an image in plain text format using 24-bit numbers, ranging from 0 to 65536, which signifies the color of a pixel. Within a PPM file, you will also find other information such as the dimensions of the image, whitespace data, and the maximum color value.
The PPM file is becoming obsolete as it uses an inefficient format and uses no compression algorithm to reduce the size of the file.
