Method Summary | |
HMatte |
getMatte()
Get any HMatte currently associated
with this component. |
void |
setMatte(HMatte m)
Applies an HMatte to this component,
for matte compositing. |
Method Detail |
public void setMatte(HMatte m) throws HMatteException
HMatte
to this component,
for matte compositing. Any existing animated matte must be
stopped before this method is called or an HMatteException will
be thrown.
m
- The HMatte
to be applied to
this component -- note that only one matte may be associated
with the component, thus any previous matte will be replaced.
If m is null, then any matte associated with the component is
removed and further calls to getMatte() shall return null. The
component shall behave as if it had a fully opaque HFlatMatte
associated with it (i.e an
HFlatMatte with the default value of 1.0.)
HMatteException
- if the HMatte
cannot be associated with the component. This can occur:
HFlatEffectMatte
or HImageEffectMatte
. The exception
is thrown even if m is null.
HMatte
public HMatte getMatte()
HMatte
currently associated
with this component.
HMatte
currently
associated with this component or null if there is no
associated matte.
