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.
