color
SYNOPSISppmtoascii
[-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 pixels 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 repreā
sents a group of 1 pixel across by 2 pixels down. With -2x4, each
character represents 2 pixels across by 4 pixels down.
