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.
