DESCRIPTION
pgmtoimgv is a simple filter for converting Portable Graymaps to grayscale Pilot Image
Viewer pdb files. The input pgm file must use the following palette unless you specify
the -4 switch:
P3
4 1
255
0 0 0
85 85 85
170 170 170
255 255 255
if you specify -4, then your grayscale image must use this palette:
P3
16 1
255
0 0 0
17 17 17
34 34 34
51 51 51

If your PGM file doesn't use one of these palettes, use ppmquant(1) to convert your
palette.
If an image's width is not a multiple of 16 pixels, enough extra white pixels will be
added at the right side to ensure alignment. Images will be padded, with white pixels, to
a width and height of 160 if needed.
