## Definition

```csharp
public enum PenLineJoin
```

## Examples

C#:

```csharp
using cAlgo.API;

namespace cAlgo
{
    // This sample shows how to use a shape Stroke Line Join
    public partial class PenLineJoinSample : Indicator
    {
        protected override void Initialize()
        {
            var rectangle = new Rectangle
            {
                HorizontalAlignment = HorizontalAlignment.Center,
                VerticalAlignment = VerticalAlignment.Center,
                StrokeLineJoin = StrokeLineJoin,
                StrokeColor = Color.Red,
                StrokeThickness = 4,
                Width = 200,
                Height = 100,
            };

            Chart.AddControl(rectangle);
        }

        public override void Calculate(int index)
        {
        }
    }
}
```

Python:

```python
import clr
clr.AddReference("cAlgo.API")

from cAlgo.API import *

class Test():
    def initialize(self):
        rectangle = Rectangle()
        rectangle.HorizontalAlignment = HorizontalAlignment.Center
        rectangle.VerticalAlignment = VerticalAlignment.Center
        rectangle.StrokeLineJoin = api.StrokeLineJoin
        rectangle.StrokeColor = Color.Red
        rectangle.StrokeThickness = 4
        rectangle.Width = 200
        rectangle.Height = 100

        api.Chart.AddControl(rectangle)
```
