- 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.
