# BaseViewer.ControlToWorkspace Method (RectangleF)

**Applies to:** Graphics Mill Web Controls · **Archived documentation**
 
Translates rectangle coordinates from the control-related coordinate system to the workspace-related one.
 
**Namespace:** [Aurigma.GraphicsMill.AjaxControls](https://www.graphicsmill.com/docs/gmwc/N_Aurigma_GraphicsMill_AjaxControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.AjaxControls (in Aurigma.GraphicsMill.AjaxControls.dll)
 
## Syntax
  
```csharp
public virtual RectangleF ControlToWorkspace(RectangleF rect
)
```
 
### Parameters
 
 - rect
     - Type: [System.Drawing..RectangleF](http://msdn2.microsoft.com/en-us/library/kwafa1d7)
Rectangle coordinates in the control coordinate system.
 
### Return Value
Rectangle coordinates in the workspace coordinate system.
 
## Remarks
  
The workspace-related coordinate system represents logical coordinates of the image loaded in the control and allows to work with it regardless of zoom, scroll or alignment. The control-related one is used to measure parameters of standard control events (e.g. position of the mouse pointer).
