NAME

       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).
