.UN description
.SH DESCRIPTION
.PP
This program is part of
.BR "Netpbm" (1)\c
\&.
.PP
\fBppmtopj\fP reads a PPM image as input and converts it into a
format suitable to be printed by an HP PaintJet printer.
.PP
For best results, the input file should be in 8-color RGB form;
i.e. it should have only
the 8 binary combinations of full-on and full-off primaries.
You could convert your input to this format like this:
.nf
pamseq 3 1 testimg.ppm >8color.pam
pnmremap -map 8color.pam testimg.pam | ppmtopj
.fi
Or you could use
.nf
ppmdither -red 2 -green 2 -blue 2
.fi

.SH OPTIONS
.PP
In addition to the options common to all programs based on libnetpbm
(most notably \fB-quiet\fP, see
.UR index.html#commonoptions
Common Options
.UE
\&), \fBppmtopj\fP recognizes the following
command line options:
.TP
\fB-rle\fP
Run length encode the image.
(This can result in larger images)
.TP
\fB-back\fP
Enhance the foreground by indicating if the background is light or
dark compared to the foreground.
.TP
\fB-render\fP \fIalg\fP
Use an internal rendering algorithm (default dither).
.TP
\fB-gamma\fP \fIint\fP
Gamma correct the image using the integer \fIint\fP as a gamma (default 0).
.TP
\fB-center\fP
Center the image to an 8.5 by 11 page
.TP
\fB-xpos\fP \fIpos\fP
Move by \fIpos\fP pixels in the x direction.
.TP
\fB-ypos\fP \fIpos\fP
Move by \fIpos\fP pixels in the y direction.
