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 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.

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.
