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



       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.

       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 aproximates 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 maxi-
       mum, 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.
