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   Common
       Options ), 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 approximately  0.6
              to 1.5.

       -dither, -cluster, -diffuse

              Alter  the rendering algorithm used for images.  These options select ordered dithering, 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 number 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 specify 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.
