ProcessForm(Stream,FormRecognitionAttributes,FormPages) Method

C#

Objective-C
Java
C++

public void ProcessForm( 
   Stream stream,
   FormRecognitionAttributes masterAttributes,
   FormPages formFields
)

'Declaration
 
Public Overloads Sub ProcessForm( _
   ByVal stream As Stream, _
   ByVal masterAttributes As FormRecognitionAttributes, _
   ByVal formFields As FormPages _
)

'Usage
 
Dim instance As AutoFormsEngine
Dim stream As Stream
Dim masterAttributes As FormRecognitionAttributes
Dim formFields As FormPages
 
instance.ProcessForm(stream, masterAttributes, formFields)

public:
void ProcessForm( 
   Stream^ stream,
   FormRecognitionAttributes^ masterAttributes,
   FormPages^ formFields
)

Parameters

stream: A System.IO.Stream containing the the unknown form image data.
masterAttributes: The Master Form attributes of the form type.
formFields: The fields to be processed for the Master Form of the form type.

This method processes the recognized form fields. The Master Form fields are obtained by calling IMasterForm.ReadFields of the AutoFormsRecognizeFormResult.MasterForm.

The stream should have all form pages.

This method is useful because it allows you to do the form processing later on or on another machine without the need to recreate the recognition result object

The form alignment is calculated internally, so providing the recognition results will speed the alignment calculation process.
