[アーティクル]
05/31/2018

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.
