NAME
rletops - Convert RLE images to PostScript
SYNOPSIS
rletops [ -C ] [ -a aspect ] [ -c center ] [ -h height ] [
-o outfile.ps ] [ -s ] [ infile ]
DESCRIPTION
Rletops converts RLE(5) images into PostScript. The
conversion uses the PostScript image operator, instructing
the device to reproduce the image to the best of its
abilities. If infile isn't specified, the RLE image is read
from stdin. The PostScript output is dumped to stdout, or
to outfile.ps, if specified.
OPTIONS
-a aspect
Specify aspect ratio of image. Default is 1.0 (note
PostScript uses square pixels).
-C Causes a color PostScript image to be generated. This
creates larger files and uses the PostScript colorimage
operator, which is not recognized by all devices. The
default is monochrome.
-c center
Centers the images about a point center inches from the
left edge of the page (or left margin if -s is
specified). Default is 4.25 inches.
-h height
Specifies the height (in inches) the image is to appear
on the page. The default is three inches. The width
of the image is calculated from the image height,
aspect ratio, and pixel dimensions.
-s Specifies image is to be generated in "Scribe Mode."
The image is generated without a PostScript showpage
operator at the end, and the default image center is
changed to 3.25 inches from the margin (which usually
is 1 inch). This is to generate PostScript files that
can be included in Scribe documents with the @Picture
command. Images may also be included in LaTex
documents with local conventions like the
\special{psfile=image.ps} command.
NOTES
On devices like the Apple LaserWriter, rletops generates
large PostScript files that take a non-trivial amount of
time to download and print. A 512x512 image takes about ten
minutes. For including images in documents at the default
sizes, 256x256 is usually sufficient resolution.

BUGS
Due to a mis-understanding with the PostScript interpreter,
rletops always rounds the image size up to an even number of
scanlines.
