NAME

       pgmmake - create a PGM image of a specified gray level and dimensions

SYNOPSIS

       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.

DESCRIPTION

       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.

EXAMPLES

           pgmmake 1 50 50

           pgmmake .2 50 100 -maxval=5
