Property Value

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

Remarks

Using modes other than Accurate may affect the results of the unknown forms recognition, but it has no effect on master forms. This Mode will work only if we select Complex method in RecognitionMethod

Example

using Leadtools.Forms.Common; 
using Leadtools.Forms.Recognition; 
using Leadtools.Codecs; 
 
///This method add a page to the form attributes. 
public void AddPageToFormAttributes(RasterImage page, FormRecognitionAttributes attributes, FormRecognitionEngine engine) 
{ 
   PageRecognitionOptions pageOptions = new PageRecognitionOptions(); 
   pageOptions.AutoCleanUp = true; 
   pageOptions.UpdateImage = true; 
   pageOptions.TradeoffMode = FormsTradeoffMode.Accurate; 
   //Page is normal page, Not a card  
   pageOptions.PageType = FormsPageType.Normal; 
   pageOptions.IncludeRectangles.Add(new LeadRect(0, 0, page.Width, page.Height)); 
   pageOptions.ExcludeRectangles.Add(new LeadRect(page.Width * 6 / 10, 
                                                          page.Height * 4 / 10, 
                                                          page.Width * 3 / 10, 
                                                          page.Height * 2 / 10)); 
   pageOptions.RegionOfInterestRectangles.Add(new LeadRect(page.Width * 1 / 10, 
                                                                   page.Height * 1 / 10, 
                                                                   page.Width * 2 / 10, 
                                                                   page.Height * 2 / 10)); 
   FormRecognitionProperties properties = engine.GetFormProperties(attributes); 
   if (properties.IsMaster) 
   { 
      engine.OpenMasterForm(attributes); 
      engine.AddMasterFormPage(attributes, page, pageOptions); 
      engine.CloseMasterForm(attributes); 
   } 
   else 
   { 
      engine.OpenForm(attributes); 
      engine.AddFormPage(attributes, page, pageOptions); 
      engine.CloseForm(attributes); 
   } 
}
