NAME
       rletops - Convert RLE images to PostScript

SYNOPSIS
       rletops	[  -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.
