NAME
       makecr -	create circumscribing rectangles in an image

SYNOPSIS
       makecr [-options]  in_file | stdin  out_file

DESCRIPTION
       makecr  finds  connected	 components of black pixels in a binary	image,
       and creates circumscribing rectangles.

       The file	format of in_file is binary pbm(5).  The  circumscribing  rec-
       tangles	are written on out_file, whose file format is d4file(4).  Each
       rectangle is denoted by a 4-tuple, the position of the left-top corner,
       the width, and the height of the	rectangle.

       If  the string "stdin" is passed	instead	of in_file, makecr reads image
       from standard input.

OPTIONS
       -bstr N
	      Add N black pixels to both ends of each horizontal black run be-
	      fore finding connected components.

       -rls N Apply  Runlength Smoothing Algorithm.  The horizontal white runs
	      which is shorter than N pixels are filled	with black pixels  be-
	      fore finding connected components.
