PageRecognitionOptions Class

Summary

Specifies the different options for a Form page when it is added to a form using FormRecognitionEngine.AddFormPage for Forms or FormRecognitionEngine.AddMasterFormPage for Master Forms.

Syntax

C++

[SerializableAttribute()] 
public class PageRecognitionOptions

  
<SerializableAttribute()> 
Public Class PageRecognitionOptions

[SerializableAttribute()] 
public ref class PageRecognitionOptions

Remarks

IncludeRectangles forms the region of the image that will be considered for feature extraction, any region outside the include region will be ignored.

If IncludeRectangles doesn't have a rectangle then the whole image will be considered as one include region for the feature extraction.

ExcludeRectangles forms the region of the image that will be ignored for feature extraction.

IncludeRectangles are considered first then the ExcludeRectangles will be excluded from the include region.

SvgDocument is the optional SVG document representation of this page if the original format supports loading as SVG. This is created and used by the recognition or processing engine.

Example

This example adds a page image to an attributes.

using Leadtools.Forms; 
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)

   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 LogicalRectangle(0, 0, page.Width, page.Height, LogicalUnit.Pixel)); 
   pageOptions.ExcludeRectangles.Add(new LogicalRectangle(page.Width * 6 / 10, 
                                                          page.Height * 4 / 10,
