TradeoffMode Property

Summary
Specifies which recognition algorithm trade-off setting to use for forms recognition and processing.

Syntax
C#
C++/CLI
Java
Python
public FormsTradeoffMode TradeoffMode { get; set; } 
public FormsTradeoffMode getTradeoffMode(); 
public void setTradeoffMode( 
   FormsTradeoffMode formsTradeoffMode 
); 
public: 
property FormsTradeoffMode TradeoffMode { 
   FormsTradeoffMode get(); 
   void set (    FormsTradeoffMode ); 
} 
TradeoffMode # get and set (AutoFormsEngine) 

Property Value

The Leadtools.Forms.Common.FormsTradeoffMode setting to use for forms recognition and processing.

Remarks

Using modes other than Accurate may affect the results of the unknown forms recognition, but it has no effect on master forms. This value may affect the results of Run(RasterImage,PageRequestCallback,Object,List<IMasterFormsCategory>), RecognizeForm(RasterImage,List<IMasterFormsCategory>), and GetMinimumRecognizedConfidenceForm.
