The Wipe effect uses Pixel Bender, which is not supported for AIR mobile applications. |
The Wipe effect performs a bitmap transition effect by running a directional wipe between the first and second bitmaps. This wipe exposes the second bitmap over the course of the animation in a direction indicated by the
direction
property.
A pixel-shader program loaded by the effect
runs the underlying bitmap effect.
If you want to use
a different Wipe behavior, you can specify a custom pixel-shader program.
The pixel-shader program must adhere to the constraints
specified for the shaderByteCode
property of AnimateTransitionShader class, and supply three additional
parameters.
The extra parameters required by the Wipe shader
are:
- An int
direction
parameter, whose value means the same as the related String property in the Wipe class. - Two floating point parameters:
imageWidth
andimageHeight
.
All of these parameters are set on the shader when the effect starts playing, so the parameters need to exist and do something appropriate in order for the effect to function correctly.
