NAME

       ppmrainbow - Generate a rainbow

SYNOPSIS

       ppmrainbow [-width=number] [-height=number]
       [-tmpdir=directory] [-verbose] color ...

       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 equals signs between an option name and its value.

DESCRIPTION

       ppmrainbow generates a PPM image that fades from one color to another to another from left to right, like a rainbow.  The colors are  those
       you specify on the command line, in that order.	The first color is added again on the right end of the image.

       If you want a vertical or other non-horizontal rainbow, run the output through pnmrotate.

       One  use  for  such  a rainbow is to compose it with another image under an alpha mask in order to add a rainbow area to another image.	In
       fact, you can make rainbow-colored text by using pbmtext, pnmcomp, and ppmrainbow.

OPTIONS

       -width number
	      The width in pixels of the output image.

	      Default is 600.

       -height number
	      The height in pixels of the output image.

	      Default is 8.

       -tmpdir
	      The directory specification of the directory ppmrainbow is to use for temporary files.

	      Default is the value of the TMPDIR environment variable, or /tmp if TMPDIR is not set.

       -verbose
	      Print the "commands" (invocations of other Netpbm programs) that ppmrainbow uses to create the image.

SEE ALSO

       ppmmake(1), pnmcomp(1), pbmtext(1), ppmfade(1), ppm(5).
