pnmtops(1) AMIGA (26 September 1991) pnmtops(1)
NAME
pnmtops - convert portable anymap to PostScript
SYNOPSIS
pnmtops [-rle|-runlength] [-scale s] [-dpi n] [-width n] [-
height n] [pnmfile]
DESCRIPTION
Reads a portable anymap as input. Produces Encapsulated
PostScript as output.
If the input file is in color (PPM), a color PostScript file
gets written. Some PostScript interpreters can't handle
color PostScript. If you have one of these you will need to
run your image through ppmtopgm first.
Note that there is no pstopnm tool - this transformation is
one-way, because a pstopnm tool would be a full-fledged
PostScript interpreter, which is beyond the scope of this
package. However, see the psidtopgm tool, which can read
grayscale non-runlength PostScript image data. Also, if
you're willing to install the fairly large GhostScript
package, it comes with a pstoppm script.
OPTIONS
The -scale flag controls the scale of the result. The
default scale is 1, which on a 300 dpi printer such as the
Apple LaserWriter makes the output look about the same size
as the input would if it was displayed on a typical 72 dpi
screen. To get one PNM pixel per 300 dpi printer pixel, use
"-scale 0.25".
The -rle or -runlength flag specifies run-length
compression. This may save time if the host-to-printer link
is slow; but normally the printer's processing time
dominates, so -rle makes things slower.
The -dpi flag lets you specify the dots per inch of your
output device. The default is 300 dpi. In theory
PostScript is device-independent and you don't have to worry
about this, but in practice its raster rendering can have
unsightly bands if the device pixels and the image pixels
aren't in sync.
The -width and -height flags let you specify the size of the
page. The default is 8.5 inches by 11 inches.
All flags can be abbreviated to their shortest unique
prefix.

BUGS
It ought to automatically rotate to landscape mode if that
would fit the image better.
