<H2>DESCRIPTION</H2>
|
|
|
|
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.
|
|
<P>
|
|
|
|
The two pixmaps must have the same size.

|
|
<B>pnmcomp</B>
|
|
|
|
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).
