20 pbmtoascii reads a PBM image as input and produces a somewhat crude
21 ASCII graphic image as output.

23 To convert back, use asciitopgm(1).

25 ppmtoterm does a similar thing for color images to be displayed on
26 color text terminals.

31 The -1x2 and -2x4 options give you two alternate ways for the pixels to
32 get mapped to characters. With 1x2, the default, each character repreā
33 sents a group of 1 pixel across by 2 pixels down. With -2x4, each
34 character represents 2 pixels across by 4 pixels down. With the 1x2
35 mode you can see the individual pixels, so it's useful for previewing
36 small images on a non-graphics terminal. The 2x4 mode lets you display
37 larger images on a small display, but it obscures pixel-level details.
38 2x4 mode is also good for displaying PGM images:

41
42 should give good results.
