# GdiGraphics.DrawBezier Method (Pen, Int32, Int32, Int32, Int32, Int32, Int32, Int32, Int32)
 
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, _x1 As Integer, _y1 As Integer, _x2 As Integer, _y2 As Integer, _x3 As Integer, _y3 As Integer, _x4 As Integer, _y4 As Integer _
)
```
 
```csharp
public void DrawBezier(Pen pen,int x1,int y1,int x2,int y2,int x3,int y3,int x4,int y4
)
```
 
### 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.

 - x1
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
X-coordinate of the start spline point.

 - y1
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
Y-coordinate of the start spline point.

 - x2
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
X-coordinate of the first control point.

 - y2
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
Y-coordinate of the first control point.

 - x3
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
X-coordinate of the second control point.

 - y3
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
Y-coordinate of the second control point.

 - x4
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
X-coordinate of the end spline point.

 - y4
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
Y-coordinate of the 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.
