# RedEyeRemoval Constructor (Rectangle, Point, Single)
 
Creates and initializes new instance of the [RedEyeRemoval](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_RedEyeRemoval.htm.md) class. Use this constructor to pass all values for the [Manual](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_RedEyeRemovalMode.htm.md) mode.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Public Sub New ( _faceRegion As Rectangle, _startPoint As Point, _sensitivity As Single _
)
```
 
```csharp
public RedEyeRemoval(Rectangle faceRegion,Point startPoint,float sensitivity
)
```
 
### Parameters
 
 - faceRegion
     - Type: [System.Drawing.Rectangle](http://msdn2.microsoft.com/en-us/1zk39146)
A [Rectangle](http://msdn2.microsoft.com/en-us/1zk39146) which specifies the face region. You can change it later using the [FaceRegion](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_RedEyeRemoval_FaceRegion.htm.md) property.

 - startPoint
     - Type: [System.Drawing.Point](http://msdn2.microsoft.com/en-us/bk9hwzbw)
A [Point](http://msdn2.microsoft.com/en-us/bk9hwzbw) which specify the point inside the red eye. Coordinates should be specified relatively left-top corner of the *faceRegion*. You can change it later using the [EyePoint](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_RedEyeRemoval_EyePoint.htm.md) property.

 - sensitivity
     - Type: [System.Single](http://msdn2.microsoft.com/en-us/3www918f)
A float value in range [0,1] which specifies a sensivity of the red eye effect removal algorithm. The smaller value you specify, more pixels are affected. You can change it later using the [Sensitivity](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_RedEyeRemoval_Sensitivity.htm.md) property.
 
## Remarks
  
When the Red Eye Removal works, it analyzes the facial features. It helps to reduce probability of malfunction. To make the red eye effect removal process as precise as possible, you should have the user to select the person's face as accurate as possible.
 
Users should select the face even if they use [Manual](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_RedEyeRemovalMode.htm.md) mode. The eye they select should be inside this rectangle.
 
When you use this constructor, the default value of the [Mode](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_RedEyeRemoval_Mode.htm.md) property is [Manual](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_RedEyeRemovalMode.htm.md).
