NAME
       ppmtoascii - convert a PPM image to ASCII graphics with ANSI terminal color

SYNOPSIS
       ppmtoascii

       [-1x2|-2x4]

       [ppmfile]

DESCRIPTION
       This program is part of Netpbm(1)

       ppmtoascii reads a PPM image as input and produces a somewhat crude ASCII graphic image as
       output, with ANSI terminal control characters so it has crude color when sent to  a  color
       text terminal.

       There is no converter for the other direction.

       ppmtoterm does a similar thing, but displays each character of the image as a single pixel
       (using the same dense character for every pixel), whereas ppmtoascii combines 2 or 8  pix-
       els into one character, where the character roughly represents those particular pixels.

       Note that ANSI provides for only eight colors (including black and white).

       Note that an ANSI terminal can't display a single character in multiple colors, so where a
       character represents 8 pixels of differing colors, the color of the character is one  that
       is the average of the colors of those pixels.

       pbmtoascii  does  the  same  thing  for	PBM  images,  with no terminal control characters
       (because none are needed for a strictly black and white image).

OPTIONS
       The -1x2 and -2x4 options give you two alternate ways for the  pixels  to  get  mapped  to
       characters.  With 1x2, the default, each character represents a group of 1 pixel across by
       2 pixels down.  With -2x4, each character represents 2 pixels across by 4 pixels down.

HISTORY

       toascii.
