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 |
---|
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
HMatte getMatte()
HMatte
currently associated
with this component.
HMatte
currently
associated with this component or null if there is no
associated matte.
