IXRKeySpline::GetControlPoint1 (Compact 2013)
3/28/2014
This method retrieves the first control point used to define a Bézier curve that describes this key spline.
Syntax
virtual HRESULT STDMETHODCALLTYPE GetControlPoint1(
XRPoint* pControlPoint1
) = 0;
Parameters
- pControlPoint1
[out] Pointer to an XRPoint structure that defines a control point that is used to manipulate the Bézier curve that describes this key spline.
Return Value
Returns an HRESULT that indicates success or failure.
Remarks
Control point 1 and control point 2 are logical points in a relative coordinate system, not points in an actual on-screen coordinate system. When a logical point is defined, the values of both x and y are expected to be between 0 and 1 inclusive.
