NAME
       ppmtopjxl - convert a portable pixmap into 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
       Reads a portable pixmap as input.  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 PaintJet printer (not an XL).

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

       The  rendering  algorithm  used	for  images  can be altered with the -dither, -cluster, and -diffuse options. These options select ordered
       dithering, clustered ordered dithering, or error diffusion respectively.  The -dark option can be used to enhance images with a dark  back-
       ground  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. This should be used only for images where quality is critical.

       The image can be resized 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 an optional dimension of `pt' (points), `dp' (decipoints), `in' (inches), or `cm' (centimetres) may
       be appended.  If only one dimension is specified, the other will be scaled appropriately.

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

       The -xscale and -yscale options can alternatively be used to scale the image by a simple factor.

       The image can be shifted on the page by using the -xshift and -yshift options. These move the image  the  specified  dimensions	right  and
       down.
