IDCompositionRectangleClip::SetBottom(IDCompositionAnimation*) method (dcomp.h)
Animates the value of the Bottom property of a clip rectangle. The Bottom property specifies the y-coordinate of the lower-right corner of the clip rectangle.
HRESULT SetBottom( [in] IDCompositionAnimation *animation );
An animation object that determines how the value of the Bottom property 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 Bottom property unless this method is called again. If the Bottom property 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 visual. The interface cannot be a custom implementation; only interfaces created by Microsoft DirectComposition can be used with this method.
