Factor by which to scale the image in a picture control or indicator.

For example, to decrease the size of the image to 50% of its original size, wire a value of 0.5 to this property. To increase the size of the image to 200% of its original size, wire a value of 2 to this property.

The value you wire to this property must be greater than or equal to 0.

If you change the zoom factor and LabVIEW draws part of the image outside the draw area of the picture control or indicator, you can use the Horizontal Scrollbar Visible and Vertical Scrollbar Visible properties to display scroll bars for the picture control or indicator.
