| File Description |
24-bit color image that is formatted in text format; each pixel is assigned a number from 0 to 65536 that defines the color of the pixel; other information stored in a PPM file includes the image height and width, whitespace data, and the maximum color value.
Because the PPM format is uncompressed and is inefficient compared to other image formats, it is seldom used for saving large image files. |
