PolyBezierTo function (wingdi.h)
The PolyBezierTo function draws one or more Bézier curves.
Syntax
BOOL PolyBezierTo(
[in] HDC hdc,
[in] const POINT *apt,
[in] DWORD cpt
);
Parameters
[in] hdc
A handle to a device context.
[in] apt
A pointer to an array of POINT structures that contains the endpoints and control points, in logical units.
[in] cpt
The number of points in the lppt array. This value must be three times the number of curves to be drawn because each Bézier curve requires two control points and an ending point.
Return value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks
This function draws cubic Bézier curves by using the control points specified by the lppt parameter. The first curve is drawn from the current position to the third point by using the first two points as control points. For each subsequent curve, the function needs exactly three more points, and uses the ending point of the previous curve as the starting point for the next.
PolyBezierTo moves the current position to the ending point of the last Bézier curve. The figure is not filled.
This function draws lines by using the current pen.
