At any point in the animation, where the
elapsed and eased fraction of the animation is f
and the pixel
values in the first and second bitmaps are v1
and v2
,
the resulting pixel value v
for any pixel in the image is:
v = v1 * (1 - f) + v2 * f
The bitmap effect is run by a pixel-shader program
that is loaded by the effect.
You can specify a different crossfade behavior by specifying
a pixel-shader program to the shaderByteCode
property.
That pixel-shader program must meet the requirements defined in the
AnimateTransitionShader effect.
