IDCompositionVisual::SetOffsetY(IDCompositionAnimation*) method (dcomp.h)

Animates the value of the OffsetY property of this visual. The OffsetY property specifies the new offset of the visual along the y-axis, relative to the parent visual.

Syntax

HRESULT SetOffsetY(
  [in] IDCompositionAnimation *animation
);

Parameters

[in] animation

Type: IDCompositionAnimation*

An animation object that determines how the value of the OffsetY property changes over time. This parameter must not be NULL.

Return value

Type: HRESULT

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.

Remarks

This method makes a copy of the specified animation. If the animation object referenced by the animation parameter is changed after this call, the change does not affect the OffsetY property unless this method is called again. If the OffsetY property was previously animated, this method replaces that 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 that created this visual. The interface cannot be a custom implementation; only interfaces created by Microsoft DirectComposition can be used with this method.
