NAME

       ppmtoterm - convert a PPM image to a ANSI ISO 6429 ascii image



SYNOPSIS

       ppmtoterm

       [ppmfile]

       All  options  can  be abbreviated to their shortest unique prefix.  You
       may use two hyphens instead of one.  You may separate  an  option  name
       and its value with white space instead of an equals sign.



DESCRIPTION

       This program is part of Netpbm(1).

       This program tries to produce an accurate representation of a PPM image
       on an terminal that implements the ANSI ISO 6429 standard.  It  aproxi-
       mates  colors, finding the minimum cartesian distance between the input
       RGB vectors and the ones in the generated palette.   As  the  available
       color palette is somewhat restricted, you get the best results when the
       colors in the original image are few and the RGB intensities are  close
       to zero, half of maximum, and maximum.

       You  can  usually  get  good results with cartoons or images with plain
       colors (no gradients).  With photos, results can vary, but are  usually
       not very accurate.

       The  output  image has one line for each row and one character for each
       column of the input image.  E.g. an 80 pixel  by  25  pixel  PPM  image
       would fill up an 80x25 terminal screen.  Use pamscale or pamcut to make
       your image fit properly on your screen.

       The image starts at the current cursor position on the terminal screen.
       Each  successive  row starts at Column 0 on the screen.  If you want to
       shift the image up or down, for example to center it, use pnmpad on the
       input.

       This  program  was  born  with  the  objective of displaying nice color
       images on the linux console, e.g. a proper logo at Linux boot.

       pbmto4425 does a similar thing for black and white images,  using  line
       drawing characters, on some terminals.



OPTIONS

       None.
