PPMTOPJXL(1) AMIGA (14 March 1991) PPMTOPJXL(1)
NAME
ppmtopjxl - convert a portable pixmap into 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
Reads a portable pixmap as input. 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 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 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. 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.
