# Matrix.RotateAt Method 
 
Applies a clockwise rotation to this [Matrix](https://www.graphicsmill.com/docs/gm/T_Aurigma_GraphicsMill_Transforms_Matrix.htm.md) around the point specified in the *point* parameter, and by prepending the rotation.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public void RotateAt(float angle,PointF point
)
```
 
### Parameters
 
 - angle
     - Type: System.Single
The angle (extent) of the rotation, in degrees.

 - point
     - Type: System.Drawing.PointF
A PointF that represents the center of the rotation.
 
## Remarks
  
The clockwise rotation is applied. Use negative angle value to rotate counter-clockwise.
 
Internally the rotation is applied by multiplying this instance of the matrix by the affine matrix of rotation. Left-sided multiplication is made.
