   FormPages pages, 
   List<PageAlignment> alignments 
)

  
Public Sub FillFieldsInformation( _ 
   ByVal form As Leadtools.RasterImage, _ 
   ByVal masterAttributes As Leadtools.Forms.Recognition.FormRecognitionAttributes, _ 
   ByVal formAttributes As Leadtools.Forms.Recognition.FormRecognitionAttributes, _ 
   ByVal pages As Leadtools.Forms.Processing.FormPages, _ 
   ByVal alignments As List(Of PageAlignment) _ 
)

public: 
void FillFieldsInformation(  
   Leadtools.RasterImage^ form, 
   Leadtools.Forms.Recognition.FormRecognitionAttributes^ masterAttributes, 
   Leadtools.Forms.Recognition.FormRecognitionAttributes^ formAttributes, 
   Leadtools.Forms.Processing.FormPages^ pages, 
   List<PageAlignment^>^ alignments 
)

Parameters

form
