Animates the value of one element of the matrix of this 3D transform.
HRESULT SetMatrixElement( int row, int column, IDCompositionAnimation *animation );
The row index of the element to change. This value must be between 0 and 3, inclusive.
The column index of the element to change. This value must be between 0 and 3, inclusive.
An animation that represents how the value of the specified element changes over time. This parameter must not be NULL.
If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.
This method makes a copy of the specified animation. If the object referenced by the animation parameter is changed after calling this method, the change does not affect the specified element unless this method is called again. If the specified element was previously animated, calling this method replaces the previous animation with the new animation.
This method fails if animation is an invalid pointer or if it was not created by the same IDCompositionDevice interface as the affected transform. The interface cannot be a custom implementation; only interfaces created by Microsoft DirectComposition can be used with this method.
