breduce(1) General Commands Manual breduce(1) 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.
