DESCRIPTION
.LP
.LP
This program is part of Netpbm.
.LP
\fBppmtopj\fR reads a PPM image as input and converts it into a
format suitable to be printed by an HP PaintJet printer.
.LP
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:
.DS L
    pamseq 3 1 testimg.ppm >8color.pam
    pnmremap -map 8color.pam testimg.pam | ppmtopj
.DE
Or you could use use
.DS L
    ppmdither -red 2 -green 2 -blue 2
.DE

OPTIONS
.LP
.RS
.IP "\fB-rle\fR"
Run length encode the image.
(This can result in larger images)
.IP "\fB-back\fR"
Enhance the foreground by indicating if the background is light or
dark compated to the foreground.
.IP "\fB-render\fR \fIalg\fR"
Use an internal rendering algorithm (default dither).
.IP "\fB-gamma\fR \fIint\fR"
Gamma correct the image using the integer \fIint\fR as a gamma (default 0).
.IP "\fB-center\fR"
Center the image to an 8.5 by 11 page
.IP "\fB-xpos\fR \fIpos\fR"
Move by \fIpos\fR pixels in the x direction.
.IP "\fB-ypos\fR \fIpos\fR"
Move by \fIpos\fR pixels in the y direction.
