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. 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 Paint-
Jet XL is approximately 0.6 to 1.5.
You an alter the rendering algorithm used for images with the -dither, -cluster, and -dif-
fuse 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.
