DESCRIPTION

16       This program is part of Netpbm(1).
17
18       ppmtopjxl  reads  a PPM image as input and produces a PCL file suitable
19       for printing on an HP PaintJet XL printer as output.
20
21       The generated file is not suitable for printing on  a  normal  PrintJet
22       printer.   The  -nopack  option generates a file which does not use the
23       normal TIFF 4.0 compression method. This file might be printable  on  a
24       normal PaintJet printer (not an XL).
25
26       The  -gamma  option sets the gamma correction for the image. The useful
27       range for the PaintJet XL is approximately 0.6 to 1.5.
28
29       You an alter the rendering algorithm used for images with the  -dither,
30       -cluster,  and  -diffuse options.  These options select ordered dither‐
31       ing, clustered ordered dithering, or error diffusion respectively.  You
32       can  use the -dark option to enhance images with a dark background when
33       they are reduced in size.  The -presentation option turns on  presenta‐
34       tion  mode, in which two passes are made over the paper to increase ink
35       density.  You should use this only for images where quality  is  criti‐
36       cal.
37
38       You can resize the image by setting the -xsize and -ysize options.  The
39       parameter to either of these options is interpreted as  the  number  of
40       dots  to  set  the  width  or height to, but you may append an optional
41       dimension of `pt' (points), `dp' (decipoints), `in' (inches),  or  `cm'
42       (centimetres).  If you specify only one dimension, ppmtopjxl will scale
43       the other one appropriately.
44
45       The options -width and -height are synonyms of -xsize and -ysize.
46
47       You can alternatively use the -xscale and -yscale options to scale  the
48       image by a simple factor.
49
50       You  can  shift  the  image  on  the  page with the -xshift and -yshift
51       options.  These move the image the specified dimensions right and down.
