PIX-BW(1)			    BRL-CAD			     PIX-BW(1)

NAME
       pix-bw -	combine	pix color planes into a	bw black and white image

SYNOPSIS
       pix-bw [-ntsc] [-crt] [-R [num]]	[-G [num]] [-B [num]] [in.pix] _
	      out.bw

DESCRIPTION
       Pix-bw will combine or select the color planes of a pix(5) format file
       from its	standard input and produce a black and white bw(5) file	on its
       standard	output.	By default all three colors are	weighted equally. The
       -ntsc uses weighting based on the NTSC primaries	and the	D6500
       alignment white.	The -crt flag applies weights for "typical" CRT
       phosphor	chromaticities and the D6500 white.

       Individual color	plane(s) can be	selected via the -R -G and -B flags.
       If one or more of these flags is	followed by a value, the value will be
       treated as a weight to be applied to that color This value is
       implicitly 1.0 divided by the number of colors selected for the flags
       which are not followed by a value.

EXAMPLES
       pix-bw -R -B _ file.pix _ file.bw will equally blend the	red and	blue
       color planes.

       pix-bw -R0.30 -G0.59 -B0.11 _ file.pix _	file.bw	has the	same effect as
       the -ntsc flag.	[The -crt weights are: 0.26, 0.66, 0.08]
