CompareDocuments Method of the Comparator Object
This method compares the original document with its copy. Both documents should have already been recognized using, for example, the Process method of the FRDocument object (or another method that performs document synthesis).
This method returns the ComparisonResult object that contains all the changes made to the document.
Syntax
C++
HRESULT CompareDocuments(
IFRDocument* RefDocument,
IFRDocument* UserDocument,
IIntsCollection* RefPageIndices,
IIntsCollection* UserPageIndices,
IComparisonResult** Result
);
C#
IComparisonResult CompareDocuments(
IFRDocument RefDocument,
IFRDocument UserDocument,
IIntsCollection RefPageIndices,
IIntsCollection UserPageIndices
);
Visual Basic .NET
Function CompareDocuments( _ RefDocument As IFRDocument, _ UserDocument As IFRDocument, _ RefPageIndices As IIntsCollection, _ UserPageIndices As IIntsCollection _ ) As IComparisonResult
Parameters
