PolyBezierTo info  Overview  Group

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. To get extended error information, call GetLastError.

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.
