.SH SYNOPSIS
.B pgmtoimgv
.RI [ -h ]

.\"----------------------------------------------------------------------------
.SH DESCRIPTION
\fBpgmtoimgv\fR is a simple filter for converting Portable Graymaps to
grayscale Pilot Image Viewer pdb files.
The input pgm file \fBmust\fR use the following palette unless you specify
the \fI-4\fR switch:
.nf
	P3
	4 1
	255
	  0   0   0
	 85  85  85
	170 170 170
	255 255 255
.fi
if you specify \fI-4\fR, then your grayscale image must use this palette:
.nf
	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
.fi
If your PGM file doesn't use one of these palettes, use \fBppmquant\fR(1)
to convert your palette.
.PP
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.
