NAME
       pgmnoise - create a PGM image made up of white noise

SYNOPSIS
       pgmnoise width height

       [-randomseed=integer]

       Minimum unique abbreviations of option are acceptable.  You may use double hyphens instead
       of single hyphen to denote options.  You may use white space in place of the  equals  sign
       to separate an option name from its value.

DESCRIPTION
       This program is part of Netpbm(1)

       pgmnoise  creates  a PGM image that is made up of pixels of random brightness.  The maxval
       is 255.

       You specify the dimensions of the image with the width and height arguments.

       The randomness in the image is limited before Netpbm 10.37 (December 2006) -- if  you  run
       the program twice in the same second, you may get identical output.

OPTIONS
       -randomseed=integer
	      This is the seed for the random number generator that generates the pixels.

	      Use this to ensure you get the same image on separate invocations.

	      By default, pgmnoise uses a seed derived from the time of day and process ID, which
	      gives you fairly uncorrelated results in multiple invocations.

	      This option was new in Netpbm 10.45 (December 2008).
