SYNOPSISppmtopjxl [-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. 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.
You an alter the rendering algorithm used for images with the -dither,
-cluster, and -diffuse options. These options select ordered dither‐
ing, 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 presenta‐
tion mode, in which two passes are made over the paper to increase ink
density. You should use this only for images where quality is criti‐
cal.
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.
