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

       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]

       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. This file might be printable on a normal Paint-
       Jet printer (not an XL).

       The  -gamma  option  sets  the gamma correction for the image. The useful range for the PaintJet XL is approxi-
       mately 0.6 to 1.5.

       You an alter the rendering algorithm used for images with the -dither, -cluster, and -diffuse  options.   These
       options  select  ordered  dithering, clustered ordered dithering, or error diffusion respectively.  You can use
       the -dark option to enhance images with a dark background when they are reduced  in  size.   The  -presentation
       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.

       You can resize the image by setting the -xsize and -ysize 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
       'pt' (points), 'dp' (decipoints), 'in' (inches), or 'cm' (centimetres).  If you  specify  only  one  dimension,
       ppmtopjxl will scale the other one appropriately.

       The options -width and -height are synonyms of -xsize and -ysize.

       You can alternatively use the -xscale and -yscale options to scale the image by a simple factor.

       You  can  shift the image on the page with the -xshift and -yshift options.  These move the image the specified
       dimensions right and down.
