This method retrieves the center of the outer ellipse of this radial gradient.

Syntax

virtual HRESULT STDMETHODCALLTYPE GetCenter(
    XRPoint* pCenter
) = 0;

Parameters

pCenter
[out] Pointer to an XRPoint structure that describes the two-dimensional center of this radial gradient.

Return Value

Returns an HRESULT that indicates success or failure.

Remarks

When the inherited method IXRGradientBrush::GetMappingMode indicates that the mapping mode is set to XRBrushMappingMode_RelativeToBoundingBox, Center (that is, the value in pCenter) and GradientOrigin are "logical points." Logical points have values between 0 and 1 and are mapped against the total size of the resulting bounding box where this brush is applied. A point value of 0.5 sets the center and gradient origin to the logical center of the bounding box.

If the mapping mode is set to XRBrushMappingMode_Absolute, Center should be supplied as a true point value in the coordinate system.
