`function PolyBezier(`
`DC: HDC;`
`Points: PPoint;`
`NumPts: Integer;`
`Filled: Boolean;`
`Continuous: Boolean`
`):Boolean;`

## Description

Use Polybezier to draw cubic Bézier curves. The first curve is drawn from the first point to the fourth point with the second and third points being the control points.

If the Continuous flag is True then each subsequent curve requires three more points, using the end-point of the previous Curve as its starting point, the first and second points being used as its control points, and the third point its end-point. If the continuous flag is set to False, then each subsequent Curve requires 4 additional points, which are used exactly as in the first curve. Any additional points which do not add up to a full Bézier(4 for Continuous, 3 otherwise) are ignored. There must be at least 4 points for an drawing to occur.

If the Filled Flag is set to True then the resulting Poly-Bézier will be drawn as a Polygon.
