Remarks

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.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
