<H2 id="description">DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>ppmtopjxl</b> reads a PPM image as input and produces a PCL file
suitable for printing on an HP PaintJet XL printer as output.
<P>The generated file is not suitable for printing on a normal
PrintJet printer. The <B>-nopack</B> option generates a file which
does not use the normal TIFF 4.0 compression method. This file might
be printable on a normal PaintJet printer (not an XL).
<P>The <B>-gamma</B> option sets the gamma correction for the
image. The useful range for the PaintJet XL is approximately 0.6 to
1.5.
<P>You an alter the rendering algorithm used for images with the
<B>-dither,</B> <B>-cluster,</B> and <B>-diffuse</B> options. These
options select ordered dithering, clustered ordered dithering, or
error diffusion respectively. You can use the <B>-dark</B> option to
enhance images with a dark background when they are reduced in size.
The <B>-presentation</B> option turns on presentation mode, in which
two passes are made over the paper to increase ink density. You
should use this only for images where quality is critical.
<P>You can resize the image by setting the <B>-xsize</B> and
<B>-ysize</B> options. The parameter to either of these options is
interpreted as the number of dots to set the width or height to, but
you may append an optional dimension of `<B>pt</B>' (points),
`<B>dp</B>' (decipoints), `<B>in</B>' (inches), or `<B>cm</B>'
(centimetres). If you specify only one dimension, <b>ppmtopjxl</b>
will scale the other one appropriately.
<P>The options <B>-width</B> and <B>-height</B> are synonyms of
<B>-xsize</B> and <B>-ysize.</B>
<P>You can alternatively use the <B>-xscale</B> and <B>-yscale</B>
options to scale the image by a simple factor.
<P>You can shift the image on the page with the <B>-xshift</B> and
<B>-yshift</B> options. These move the image the specified dimensions
right and down.
