IDCompositionTranslateTransform::SetOffsetX(float) method (dcomp.h)
Changes the value of the OffsetX property of a 2D translation transform. The OffsetX property specifies the distance to translate along the x-axis.
Syntax
HRESULT SetOffsetX(
[in] float offsetX
);
Parameters
[in] offsetX
Type: float
The distance to translate along the x-axis, in pixels.
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 performs an affine transformation, which moves every point by a fixed distance in the same direction. It is similar to shifting the origin of the coordinate space.
This method fails if the offsetX parameter is NaN, positive infinity, or negative infinity.
If the OffsetX property was previously animated, this method removes the animation and sets the OffsetX property to the specified static value.
