About PBM
Portable Bitmap
The 1-bit black and white member of the Netpbm family: uncompressed pixels after a short text header. Use it as monochrome input for tools such as potrace and fax or OCR utilities.
About PGM

The grayscale member of the Netpbm family: uncompressed pixels after a short text header. Use it to feed grayscale images to computer vision and image-processing code that reads Netpbm.
