breduce - read a portable bitmap and reduce it to 1/N
breduce [-options] in_file | - [out_file]
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
Document Image Processing. Black pixels have priority over white pixels on
the reduction process. Consequently, thin black lines are kept continuous 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.
