Interface Summary

Interface	Description
ITessAPI	An interface represents common TessAPI classes/constants.
ITessAPI.CANCEL_FUNC	Callback for cancel_func.
ITessAPI.TessCancelFunc
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.
ITessAPI.TessOrientation	+------------------+ | 1 Aaaa Aaaa Aaaa | | Aaa aa aaa aa | | aaaaaa A aa aaa.
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.
ITessAPI.TessPageSegMode	Possible modes for page layout analysis.
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.
ITessAPI.TessPolyBlockType	Possible types for a POLY_BLOCK or ColPartition.
ITessAPI.TessProgressFunc
ITessAPI.TessTextlineOrder	The text lines are read in the given sequence. In English, the order is top-to-bottom.
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.
ITesseract	An interface represents common OCR methods.
TessAPI	A Java wrapper for Tesseract OCR 5.3.3 API using JNA Interface Mapping.

Class Summary

Class	Description
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.
ITessAPI.ETEXT_DESC	Description of the output of the OCR engine.
ITessAPI.TessBaseAPI	Base class for all tesseract APIs.
ITessAPI.TessChoiceIterator
ITessAPI.TessMutableIterator	MutableIterator adds access to internal data structures.
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.
ITessAPI.TessResultIterator	Iterator for tesseract results that is capable of iterating in proper reading order over Bi Directional (e.g.
ITessAPI.TessResultRenderer	Interface for rendering tesseract results into a document, such as text, HOCR or pdf.
ITessAPI.TimeVal
OCRResult	Encapsulates Tesseract OCR results at file level.
TessAPI1	A Java wrapper for Tesseract OCR 5.3.3 API using JNA Direct Mapping.
Tesseract	An object layer on top of TessAPI, provides character recognition support for common image formats, and multi-page TIFF images beyond the uncompressed, binary TIFF format supported by Tesseract OCR engine.
Tesseract1	An object layer on top of TessAPI1, provides character recognition support for common image formats, and multi-page TIFF images beyond the uncompressed, binary TIFF format supported by Tesseract OCR engine.
Word	Encapsulates Tesseract OCR results at certain page iterator level.
