Each pixel value is represented by an individual integer in an ascii encoded pbm or pgm or ppm file. For example an rgb color depth of 8 indicates that each of the red green and blue components are represented by an 8 bit value. These files are large and uncompressed but the images are rich in color high in quality simple and compatible in all windows os and programs.
