IXRKeySpline::SetControlPoint1 (Windows Embedded CE 6.0)
1/6/2010
This method sets the first control point used to define a Bézier curve that describes this key spline.
Syntax
virtual HRESULT STDMETHODCALLTYPE SetControlPoint1(
XRPoint* pControlPoint1
) = 0;
Parameters
- pControlPoint1
[in] 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.
