PolyBezierTo

The PolyBezierTo function draws one or more Bézier curves.

BOOL PolyBezierTo(

HDC hdc,	// handle to device context
CONST POINT *lppt,	// pointer to endpoints and control points
DWORD cCount	// count of endpoints and control points
);

Parameters

hdc

Identifies a device context.

lppt

Points to an array of POINT structures that contains the endpoints and control points.

cCount

Specifies 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 Values

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.
