 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public sealed class AutoCrop : Transform

## Remarks
  
This transform supports two settings:
 
- **[BorderColor](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Transforms_AutoCrop_BorderColor.htm.md)** The color of the border to remove.

using (var bitmap = new Bitmap(@"Images\in.jpg"))
using (var autoCrop = new AutoCrop(RgbColor.Brown))

        result.Save(@"Images\Output\out.jpg");
