pgmmake - Man Page

create a PGM image of a specified gray level and dimensions

Examples (TL;DR)


pgmmake [-maxval=maxval] graylevel width height

All options can be abbreviated to their shortest unique prefix. You may use two hyphens instead of one to designate an option.  You may use either white space or an equals sign between an option name and its value.


This program is part of Netpbm(1).

pgmmake produces a PGM image of the specified gray level, width, height, and maxval.

Specify the gray level (graylevel) as a decimal floating point number in the range [0, 1].  E.g. 1 is white, 0 is black, and 0.5 is half luminosity gray.


    pgmmake 1 50 50
    pgmmake .2 50 100 -maxval=5


In addition to the options common to all programs based on libnetpbm (most notably -quiet, see Common Options ), pgmmake recognizes the following command line option:


    The maxval for the generated image.  Default is 255.
