NAME
       breduce - read a	portable bitmap	and reduce it to 1/N

SYNOPSIS
       breduce [-options]  in_file | -	[out_file]

DESCRIPTION
       breduce	reads  a  portable  bitmap as input, reduces it	by a factor of
       1/N, and	produces a portable bitmap as output.

       This program is similar to pbmreduce(4),	but is specialized  for	 Docu-
       ment Image Processing.  Black pixels have priority over white pixels on
       the reduction process. Consequently, thin black lines are kept continu-
       ous on the image, while thin white lines	may be broken.

       If  the	string	"-"  is	passed instead of in_file, breduce reads image
       from standard input.  If	the output file	 out_file  is  not  specified,
       breduce writes image to standard	output.

OPTIONS
       -div N Division factor. The image is reduced to 1/N.  Note that N is an
	      integer.	The default value is N=2.

       -quiet Suppress messages.
