pbmreduce

Proportionally reduce a PBM image. See also: pamenlarge, pamditherbw. More information: https://netpbm.sourceforge.net/doc/pbmreduce.html.

  • Reduce the specified image by the specified factor:

pbmreduce {{N}} {{path/to/image.pbm}} > {{path/to/output.pbm}}

  • Use simple thresholding when reducing:

pbmreduce -threshold {{N}} {{path/to/image.pbm}} > {{path/to/output.pbm}}

  • Use the specified threshold for all quantizations:

pbmreduce -value {{0.6}} {{N}} {{path/to/image.pbm}} > {{path/to/output.pbm}}
