PGMTOIMGV(1)		    General Commands Manual		  PGMTOIMGV(1)

NAME
       pgmtoimgv  -  Portable Graymap to Pilot Image Viewer converter, version
       2.0.

SYNOPSIS
       pgmtoimgv [-h] [-v] [-4]	[-t title] [-n notefile] [-{c|m|u}] [in	[out]]

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
	     68	 68  68
	     85	 85  85
	    102	102 102
	    119	119 119
	    136	136 136
	    153	153 153
	    170	170 170
	    187	187 187
	    204	204 204
	    221	221 221
	    238	238 238
	    255	255 255
       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.

OPTIONS
       -h     Display a	short summary of the command line options and exit.

       -m     Produce  a  compressed  image  if	 it is smaller than the	uncom-
	      pressed version.	This is	the default compression	mode.
