The PolyBezier function draws one or more Bézier curves.
BOOL PolyBezier(
HDC hdc, |
// handle to device context |
CONST POINT *lppt, |
// pointer to endpoints and control points |
DWORD cPoints |
// count of endpoints and control points |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Th Polybezier function draws cubic Bézier curves by using the endpoints and control points specified by the lppt parameter. The first curve is drawn from the first point to the fourth point by using the second and third points as control points. Each subsequent curve in the sequence needs exactly three more points: the ending point of the previous curve is used as the starting point, the next two points in the sequence are control points, and the third is the ending point.
The current position is neither used nor updated by the PolyBezier function. The figure is not filled.
This function draws lines by using the current pen.
