Enum RecognitionAlgorithm

Namespace

GrapeCity.Documents.Pdf.Recognition

Assembly

GcDocs.Pdf.dll

Defines possible algorithms that can be used to recognize the logical structure of a PDF when building text maps.

public enum RecognitionAlgorithm

Fields

AcrobatLike = 1

Algorithm that primarily relies on the physical structure of a PDF when building text maps. Results yielded by this algorithm are consistent with how Acrobat Reader handles text when searching, selecting etc.

Advanced = 0

Advanced algorithm that employs various heuristics and strategies to try to correctly recognize the logical document structure when building text maps.

Please note that because the details of this algorithm may change from version to version, the text maps for a specific PDF may also change when GcPdf is updated.
