# GdiGraphics.DrawPolygon Method (Pen, Point[])
 
Draws a polygon.
 
**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 DrawPolygon ( _pen As Pen, _points As Point() _
)
```
 
```csharp
public void DrawPolygon(Pen pen,Point[] points
)
```
 
### 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 outline a polygon.

 - points
     - Type:  [System.Drawing.Point](http://msdn2.microsoft.com/en-us/bk9hwzbw) []
Array of coordinates of the polygon vertices.
 
## Remarks
 Polyline can be treated as closed polyline, where last point is connected with the first one. 
All the coordinates are measured in units specified with [Unit](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_UnitConverterObject_Unit.htm.md) property.

To fill the polygon, use [FillPolygon(Brush, Point\[\], FillMode)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Drawing_GdiGraphics_FillPolygon_3_bab9d460.htm.md) method.
 
## Examples
  
```
Dim bitmap As New Aurigma.GraphicsMill.Bitmap( _
 Aurigma.GraphicsMill.RgbColor.White, 185, 145, _
 Aurigma.GraphicsMill.PixelFormat.Format24bppRgb)

Dim graphics As Aurigma.GraphicsMill.Drawing.GdiGraphics = bitmap.GetGdiGraphics()

'Draw filled and outlined rectangle
Dim pen As New Aurigma.GraphicsMill.Drawing.Pen(Aurigma.GraphicsMill.RgbColor.Red, 3)
Dim brush As New Aurigma.GraphicsMill.Drawing.SolidBrush( _
 Aurigma.GraphicsMill.RgbColor.FromRgb(&HDD, &HDD, &HFF))
graphics.FillRectangle(brush, 10, 10, 100, 60)
graphics.DrawRectangle(pen, 10, 10, 100, 60)

'Draw filled but non-outlined ellipse
brush.Color = Aurigma.GraphicsMill.RgbColor.Yellow
graphics.FillEllipse(brush, 60, 40, 100, 80)

'Draw outlined but non-filled polygon 
pen.Color = Aurigma.GraphicsMill.RgbColor.Green
pen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot
pen.Width = 1
Dim points As System.Drawing.Point() = { _
 New System.Drawing.Point(20, 30), New System.Drawing.Point(50, 2), _
 New System.Drawing.Point(180, 30), New System.Drawing.Point(80, 140)}
graphics.DrawPolygon(pen, points)
```
 
```csharp
Aurigma.GraphicsMill.Bitmap bitmap = new Aurigma.GraphicsMill.Bitmap(
    Aurigma.GraphicsMill.RgbColor.White, 185, 145, 
    Aurigma.GraphicsMill.PixelFormat.Format24bppRgb);

Aurigma.GraphicsMill.Drawing.GdiGraphics graphics = bitmap.GetGdiGraphics();

//Draw filled and outlined rectangle
Aurigma.GraphicsMill.Drawing.Pen pen = new Aurigma.GraphicsMill.Drawing.Pen(
    Aurigma.GraphicsMill.RgbColor.Red, 3);
Aurigma.GraphicsMill.Drawing.SolidBrush brush = new Aurigma.GraphicsMill.Drawing.SolidBrush( 
    Aurigma.GraphicsMill.RgbColor.FromRgb(0xDD, 0xDD, 0xFF));
graphics.FillRectangle(brush, 10, 10, 100, 60);
graphics.DrawRectangle(pen, 10, 10, 100, 60);

//Draw filled but non-outlined ellipse
brush.Color = Aurigma.GraphicsMill.RgbColor.Yellow;
graphics.FillEllipse(brush, 60, 40, 100, 80);

//Draw outlined but non-filled polygon 
pen.Color = Aurigma.GraphicsMill.RgbColor.Green;
pen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot;
pen.Width = 2;
System.Drawing.Point[] points = { 
    new System.Drawing.Point(20, 30), new System.Drawing.Point(50, 2), 
    new System.Drawing.Point(180, 30), new System.Drawing.Point(80, 140)};
graphics.DrawPolygon(pen, points);
```
