ITransformProperty::AddPoint method
The AddPoint method adds a data point to the property.
Syntax
HRESULT AddPoint(
[in] double dblTime,
[in] PROPVARIANT varpropValue,
[out] ITransformPropertyPoint **ppCreatedPoint
);
Parameters
-
dblTime [in]
-
The time that is associated with this point.
-
varpropValue [in]
-
The value that is associated with this point.
-
ppCreatedPoint [out]
-
Address of a pointer to a copy of the created and added point. The caller must release this interface when it is no longer needed.
Return value
The method returns an HRESULT of S_OK for success, or a standard COM error code for failure.
Remarks
If a point at the time specified already exists, this method will add a duplicate point with the same time and a new value. Therefore, you should always check first to see if the time point exists, and if so, use SetValueAtTime instead.
