NAME
       avs2ps - convert AVS image input on stdin to monochrome PostScript on stdout

SYNOPSIS
	  avs2ps [-b] [-dpi xxx] < infile.avs > outfile.ps

       avs2ps converts a 24-bit color image file in AVS format into a dithered monochrome PostScript image with the same number of pixels as the
       input file.  avs2ps may be used as a filter for the output of the render program to produce a PostScript file directly.

       avs2ps is machine independent, and does not impose restrictions on the tile size in the original image.	It supersedes the programs mol-
       ras3d and hdither in the viewtools package.

EXAMPLES
       Produce an unbordered black & white image suitable for printing on a 300 dpi PostScript printer.

	    render < infile.r3d | avs2ps > image.ps

       Add a border, and prepare image for a 400dpi printer

	    render < infile.r3d | avs2ps -b -dpi 400 > image.ps

OPTIONS
       -b

       Draw a border around the figure.  By default avs2ps will produce a borderless image 0.5 inch in from the bottom left of the page.

       -dpi xxx

       By default avs2ps writes header records into the PostScript output file which are correct for a 300dpi printer (e.g. an HP IIIsi).  If
       there is a mis-match between the header records and the actual resolution of the printer the image quality is substantially degraded.  This
       option allows one to specify a different printer resolution (e.g. -dpi 400 for a Next printer, or -dpi 95 for GhostScript on a 1280x1024
       workstation screen).

DESCRIPTION
       avs2ps converts the input stream to a grey scale image and then applies an empirical algorithm for dithering and error propagation to pro-
       duce a monochrome output image.
