DESCRIPTION
Reads a portable pixmap as input. Produces a PCL file
suitable for printing on an HP PaintJet XL printer as out
put.
The generated file is not suitable for printing on a nor
mal 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.
The rendering algorithm used for images can be altered
with the -dither, -cluster, and -diffuse options. These
options select ordered dithering, clustered ordered
dithering, or error diffusion respectively. The -dark
option can be used to enhance images with a dark back
ground 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. This should
be used only for images where quality is critical.
The image can be resized 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 an optional dimension of `pt' (points),
`dp' (decipoints), `in' (inches), or `cm' (centimetres)
may be appended. If only one dimension is specified, the
other will be scaled appropriately.
The options -width and -height are synonyms of -xsize and
-ysize.
The -xscale and -yscale options can alternatively be used
to scale the image by a simple factor.
The image can be shifted on the page by using the -xshift
and -yshift options. These move the image the specified
dimensions right and down.
