    Interface
    Description
    static interface 
    ITessAPI.CANCEL_FUNC
    Callback for cancel_func.
    static class 
    ITessAPI.EANYCODE_CHAR
    It should be noted that the format for char_code for version 2.0 and beyond is UTF-8, which means that ASCII characters will come out as one structure but other characters will be returned in two or more instances of this structure with a single byte of the UTF-8 code in each, but each will have the same bounding box.

    Programs which want to handle languages with different characters sets will need to handle extended characters appropriately, but all code needs to be prepared to receive UTF-8 coded characters for characters such as bullet and fancy quotes.
    static class 
    ITessAPI.ETEXT_DESC
    Description of the output of the OCR engine.
    static class 
    ITessAPI.TessBaseAPI
    Base class for all tesseract APIs.
    static interface 
    ITessAPI.TessCancelFunc
     
    static class 
    ITessAPI.TessChoiceIterator
     
    static class 
    ITessAPI.TessMutableIterator
    MutableIterator adds access to internal data structures.
    static interface 
    ITessAPI.TessOcrEngineMode
    When Tesseract/Cube is initialized we can choose to instantiate/load/run only the Tesseract part, only the Cube part or both along with the combiner.
    static interface 
    ITessAPI.TessOrientation
    +------------------+ | 1 Aaaa Aaaa Aaaa | | Aaa aa aaa aa | | aaaaaa A aa aaa.
    static class 
    ITessAPI.TessPageIterator
    Class to iterate over tesseract page structure, providing access to all levels of the page hierarchy, without including any tesseract headers or having to handle any tesseract structures.
    WARNING! This class points to data held within the TessBaseAPI class, and therefore can only be used while the TessBaseAPI class still exists and has not been subjected to a call of Init, SetImage, Recognize, Clear, End DetectOS, or anything else that changes the internal PAGE_RES.
    static interface 
    ITessAPI.TessPageIteratorLevel
    Enum of the elements of the page hierarchy, used in ResultIterator to provide functions that operate on each level without having to have 5x as many functions.
    static interface 
    ITessAPI.TessPageSegMode
    Possible modes for page layout analysis.
    static interface 
    ITessAPI.TessParagraphJustification
    NOTA BENE: Fully justified paragraphs (text aligned to both left and right margins) are marked by Tesseract with JUSTIFICATION_LEFT if their text is written with a left-to-right script and with JUSTIFICATION_RIGHT if their text is written in a right-to-left script.

    Interpretation for text read in vertical lines: "Left" is wherever the starting reading position is.
    static interface 
    ITessAPI.TessPolyBlockType
    Possible types for a POLY_BLOCK or ColPartition.
    static interface 
    ITessAPI.TessProgressFunc
     
    static class 
    ITessAPI.TessResultIterator
    Iterator for tesseract results that is capable of iterating in proper reading order over Bi Directional (e.g.
    static class 
    ITessAPI.TessResultRenderer
    Interface for rendering tesseract results into a document, such as text, HOCR or pdf.
    static interface 
    ITessAPI.TessTextlineOrder
    The text lines are read in the given sequence.

    In English, the order is top-to-bottom.
    static interface 
    ITessAPI.TessWritingDirection
    The grapheme clusters within a line of text are laid out logically in this direction, judged when looking at the text line rotated so that its Orientation is "page up".

    For English text, the writing direction is left-to-right.
