RLETOPS(1)RLETOPS(1)NAMErletops - Convert RLE images to PostScript
SYNOPSISrletops [ -C ] [ -a aspect ] [ -c center ] [ -h height ] [ -o out‐
file.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 dimen‐
sions.
-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 Post‐
Script files that can be included in Scribe documents with the
@Picture command. Images may also be included in LaTex docu‐
ments with local conventions like the \special{psfile=image.ps}
command.
NOTES
On devices like the Apple LaserWriter, rletops generates large Post‐
Script 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 reso‐
lution.

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