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).
