# Matrix.RotateAt Method (Single, PointF)
 
Applies a rotate affine transform to the matrix around the specified point.
 
**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 RotateAt ( _angle As Single, _point As PointF _
)
```
 
```csharp
public void RotateAt(float angle,PointF point
)
```
 
### Parameters
 
 - angle
     - Type: [System.Single](http://msdn2.microsoft.com/en-us/3www918f)
The angle of the rotation (in degrees).

 - point
     - Type: [System.Drawing.PointF](http://msdn2.microsoft.com/en-us/ckys1c1e)
The point which is used as a 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. If you need to make right-sided multiplication, you can use an [overloaded version](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Transforms_Matrix_RotateAt_3_2e4163b7.htm.md) of this method which enables to specify a matrix order.
