BWCROP(1)			    BRL-CAD			     BWCROP(1)

NAME
       bwcrop -	crop black and white bw	files

SYNOPSIS
       bwcrop in.bw out.bw

       bwcrop in.bw out.bw inwidth outwidth outheight ulx uly urx ury lrx lry
	      llx lly

DESCRIPTION
       Bwcrop crops any	quadrilateral out of an	arbitrarily large bw(5)	input
       file (in.bw), squares that region to a given height and width output
       size, and writes	the result to out.bw. The first	form of	bwcrop prompts
       for all parameters it needs to do the cropping. All responses should be
       pixel counts or first quadrant coordinates. The second form allows all
       of the needed parameters	to be given on the command line	and is
       intended	for use	from shell scripts. The	coordinate names stand for
       upper-left-x, lower-right-y, etc.

       The nearest input pixel is selected for each output pixel. No
       interpolation is	done by	this program.
