This property sets the vertical scaling (magnification). This property is only enabled when using a custom-built user interface (UserInterface=Suppress).
Property Value
YScaling is the vertical scaling
Default value is 1.0
Explanation
The YScaling property sets the vertical scaling (magnification). This property is only enabled when the UserInterface property is Suppress. If the UserInterface is set to a value other than Suppress or if a digital camera is being used, this property is disabled. The range and values of scaling supported by the scan device can be retrieved by executing the GetCapabilityEnumToSingle or the GetCapabilityRange method.
To scan in actual size, set the XScaling and YScaling properties to 1.0
Note: Although it is possible to set different values for horizontal and vertical scaling some datasources (scan drivers) do not support this. In such cases, either the horizontal scaling value or the vertical scaling value will be used.
