pgmmake - Man Page

• Create PGM image with a uniform gray level (specified as a number between 0 and 1) and the specified dimensions: pgmmake graylevel width height > path/to/output_file.pgm

tldr.sh

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:

-maxval=maxval

    The maxval for the generated image.  Default is 255.

With older Netpbm, use ppmmake and ppmtopgm.
