NAME
       ppmtopjxl - convert a PPM image to an HP PaintJet XL PCL file


SYNOPSIS
       ppmtopjxl  [-nopack]  [-gamma  n]  [-presentation]  [-dark]  [-diffuse]  [-cluster] [-dither]
       [-xshift   s]   [-yshift   s]   [-xshift   s]   [-yshift   s]   [{-xsize|-width|-xscale}   s]
       [{-ysize|-height|-yscale} s] [ppmfile]


DESCRIPTION
       This program is part of Netpbm(1).

       ppmtopjxl  reads  a PPM image as input and produces a PCL file suitable for printing on an HP
       PaintJet XL printer as output.

       The generated file is not suitable for printing on a normal PrintJet  printer.   The  -nopack
       option  generates  a  file which does not use the normal TIFF 4.0 compression method and thus
       might be printable on a normal PaintJet printer (not an XL).


OPTIONS
       In addition to the options common to all programs based on libnetpbm  (most  notably  -quiet,
       see ]8;;index.html#commonoptions\ Common Options]8;;\ ), ppmtopjxl recognizes the following command line options:




       -nopack

              Generate  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).


       -gamma

              Set the gamma correction for the image. The useful range for the PaintJet  XL  is  ap‐
              proximately 0.6 to 1.5.


       -dither, -cluster, -diffuse

              Alter  the  rendering algorithm used for images.  These options select ordered dither‐
              ing, clustered ordered dithering, or error diffusion respectively.


       -dark

              Enhance images with a dark background when they are reduced in size.


       -presentation

              Turn 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.


       -xsize, -ysize

              Resize the image.  The parameter to either of these options is interpreted as the num‐
              ber of dots to set the width or height to, but you may append an optional dimension of
              `pt' (points), `dp' (decipoints), `in' (inches), or `cm' (centimetres).  If you  spec‐
              ify only one dimension, ppmtopjxl will scale the other one appropriately.


       -width, -height

              Synonyms of -xsize and -ysize.


       -xscale, -yscale

              Alternatives to -xsize and -ysize.  Scale the image by a simple factor.


       -xshift, -yshift

              Shift  the image on the page.  These move the image the specified dimensions right and
              down.
