ppmrainbow(1)               General Commands Manual              ppmrainbow(1)

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  ppm-
       rainbow.

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.
