# RotateAndFlip Class
 
This class enables you to flip the bitmap or rotate it on angle divisible on 90 degrees.
 
**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 NotInheritable Class RotateAndFlip _Inherits BitmapTransform
```
 
```csharp
public sealed class RotateAndFlip : BitmapTransform
```
 
## Remarks
 This transform has the single parameter [Mode](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_RotateAndFlip_Mode.htm.md). It enables all combination of rotation on angle divisible on 90 degree and flipping by both axes. Rotation made by this transform works faster than one made by [Rotate](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_Rotate.htm.md) (which enables you to do rotate on arbitrary angle).
 
## Examples
  
```
Dim rotateAndFlip As New Aurigma.GraphicsMill.Transforms.RotateAndFlip
rotateAndFlip.Mode = System.Drawing.RotateFlipType.Rotate90FlipNone
rotateAndFlip.ApplyTransform(bitmap)
```
 
```csharp
Aurigma.GraphicsMill.Transforms.RotateAndFlip rotateAndFlip =
    new Aurigma.GraphicsMill.Transforms.RotateAndFlip();
rotateAndFlip.Mode = System.Drawing.RotateFlipType.Rotate90FlipNone;
rotateAndFlip.ApplyTransform(bitmap);
```
