PIXDIFF(1)			    BRL-CAD			    PIXDIFF(1)

NAME
       pixdiff - highlight pixel colors	which differ between two files

SYNOPSIS
       pixdiff file1.pix file2.pix _ out.pix

DESCRIPTION
       Pixdiff highlights the pixels which differ between two color pix(5)
       format files. The input files are read pixel by pixel and if any	of the
       color planes red, green,	or blue	differ,	those colors are specially
       marked. Bytes that differ by +/-1 are drawn with	intensity 192, bytes
       that differ more	are displayed at full intensity	of 255.	If none	of the
       color values differ, an NTSC converted black and	white equivalent at
       one half	the original intensity is displayed. This is to	aid in seeing
       where in	the image the different	pixels lie. Upon completion, pixdiff
       reports the number of bytes matching, the number	off by 1, and the
       number off by many.

       Also see	bwdiff(1) which	can still be used on pix files,	yet can
       produce different kinds of output.
