Interface HMatte

All Known Implementing Classes:

HFlatEffectMatte, HFlatMatte, HImageEffectMatte, HImageMatte

public interface HMatte

HMatte is the base interface for all matte classes.

Where pixels in a component already have an alpha value (e.g. from an image), the alpha value from the component and the alpha value from the HMatte are multiplied together to obtain the actual alpha value to be used for that pixel.

The final displayed value of the component and its HMatte is obviously subject to the capabilities of the underlying hardware platform.
