# Module Image.PNM

Description

  This submodule keeps the PNM encode/decode capabilities of the Image module.

  PNM is a common image storage format on unix systems, and is a very simple format.

  This format doesn't use any color palette.

  The format is divided into seven subformats;

      P1(PBM) - ascii bitmap (only two colors)
      P2(PGM) - ascii greymap (only grey levels)
      P3(PPM) - ascii truecolor
      P4(PBM) - binary bitmap
      P5(PGM) - binary greymap
      P6(PPM) - binary truecolor
      P7 - binary truecolor (used by xv for thumbnails)

  Simple encoding:
  encode ,
  encode_binary ,
  encode_ascii

  Simple decoding:
  decode

  Advanced encoding:
  encode_P1 ,
  encode_P2 ,
  encode_P3 ,
