    AcrobatLikeAlgorithm 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.
    AdvancedAdvanced 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.
