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.
