**Namespace:** [Aurigma.GraphicsMill.WinControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WinControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WinControls (in Aurigma.GraphicsMill.WinControls.dll)

## Remarks
  
When this navigator is attached to the [BitmapViewer](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_BitmapViewer.htm.md) using its property [Navigator](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_WinControls_ViewerBase_Navigator.htm.md), it is working in the following way:
 
1. When the left button of the mouse is clicked, it zooms the image out.
2. When the right button of the mouse is clicked, it zooms the image in.
