# GdiGraphics.DrawBezier Method (Pen, PointF, PointF, PointF, PointF)
 
Draws a cubic Bezier spline.
 
**Namespace:** [Aurigma.GraphicsMill.Drawing](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Drawing.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Public Sub DrawBezier ( _pen As Pen, _pt1 As PointF, _pt2 As PointF, _pt3 As PointF, _pt4 As PointF _
)
```
 
```csharp
public void DrawBezier(Pen pen,PointF pt1,PointF pt2,PointF pt3,PointF pt4
)
```
 
### Parameters
 
 - pen
     - Type: [Aurigma.GraphicsMill.Drawing.Pen](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Drawing_Pen.htm.md)
 [Pen](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Drawing_Pen.htm.md) object which is used to draw an spline.

 - pt1
     - Type: [System.Drawing.PointF](http://msdn2.microsoft.com/en-us/ckys1c1e)
Start spline point.

 - pt2
     - Type: [System.Drawing.PointF](http://msdn2.microsoft.com/en-us/ckys1c1e)
First control point.

 - pt3
     - Type: [System.Drawing.PointF](http://msdn2.microsoft.com/en-us/ckys1c1e)
Second control point.

 - pt4
     - Type: [System.Drawing.PointF](http://msdn2.microsoft.com/en-us/ckys1c1e)
End spline point.
 
## Remarks
  
A Bezier spline is defined with four points: first and last point specify beginning and end of the curve, second and third points specify so-called control points. The control points act as magnets, pulling the curve in certain directions to influence the way the Bezier spline bends.
 
All the coordinates are measured in units specified with [Unit](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_UnitConverterObject_Unit.htm.md) property.
