ppmmix - blend together two portable pixmaps


SYNOPSIS

       ppmmix fadefactor ppmfile1 ppmfile2


DESCRIPTION

       Reads  two  portable pixmaps as input. Mixes them together
       using the specified fade factor. The fade factor may be in
       the  range  from  0.0  (only ppmfile1's image data) to 1.0
       (only ppmfile2's image data).  Anything in between gains a
       smooth blend between the two images.

       The two pixmaps must have the same size.

       pnmcomp  is  a more general alternative.  It allows you to
       mix images of different size and to have the  fade  factor
       vary  throughout  the  image  (through the use of an alpha
       mask).
