### Property Value
A number that specifies a current zoom value.
 
## Remarks
  
Zoom values are measured in percents/100. It means that value = 1 specifies the 100% zoom (actual size), value = 10 means 1000% zoom (10x magnification), value = 0,5 means 50% zoom (half of the original size), and so on.
 
The default value is **1**.
 
**Note** 
Note, when [ZoomMode](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_WinControls_ViewerBase_ZoomMode.htm.md) is not [None](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_WinControls_ZoomMode.htm.md), this property is ignored.
