pbmreduce

pbmreduce(1)						      General Commands Manual						      pbmreduce(1)

NAME

       pbmreduce - read a portable bitmap and reduce it N times

SYNOPSIS

       pbmreduce [-floyd|-fs|-threshold ] [-value val] N [pbmfile]

DESCRIPTION

       Reads a portable bitmap as input.  Reduces it by a factor of N, and produces a portable bitmap as output.

       pbmreduce  duplicates  a  lot  of  the  functionality  of pgmtopbm; you could do something like pnmscale | pgmtopbm, but pbmreduce is a lot
       faster.

       pbmreduce can be used to "re-halftone" an image.  Let's say you have a scanner that only produces black&white, not grayscale, and it does a
       terrible job of halftoning (most b&w scanners fit this description).  One way to fix the halftoning is to scan at the highest possible res-
       olution, say 300 dpi, and then reduce by a factor of three or so using pbmreduce.  You can even correct the  brightness	of  an	image,	by
       using the -value flag.

OPTIONS

       By  default,  the  halftoning after the reduction is done via boustrophedonic Floyd-Steinberg error diffusion; however, the -threshold flag
       can be used to specify simple thresholding.  This gives better results when reducing line drawings.

       The -value flag alters the thresholding value for all quantizations.  It should be a real number between 0 and 1.  Above 0.5  means  darker
       images; below 0.5 means lighter.

       All flags can be abbreviated to their shortest unique prefix.
