ClassDescriptionAn interface represents common TessAPI classes/constants.Callback for
cancel_func.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.Description of the output of the OCR engine.Base class for all tesseract APIs.MutableIterator adds access to internal data structures.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.+------------------+ | 1 Aaaa Aaaa Aaaa | | Aaa aa aaa aa | | aaaaaa A aa aaa. | | 2 | | ####### c c C | | ####### c c c | | < ####### c c c | | < ####### c c | | < ####### .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!Enum of the elements of the page hierarchy, used inResultIteratorto provide functions that operate on each level without having to have 5x as many functions.Possible modes for page layout analysis.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.Possible types for a POLY_BLOCK or ColPartition.Iterator for tesseract results that is capable of iterating in proper reading order over Bi Directional (e.g. mixed Hebrew and English) text.Interface for rendering tesseract results into a document, such as text, HOCR or pdf.The text lines are read in the given sequence.
In English, the order is top-to-bottom.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.An interface represents common OCR methods.Rendered formats supported by Tesseract.Encapsulates Tesseract OCR results at file level.Encapsulates Tesseract Orientation Script Detection (OSD) results.A Java wrapper forTesseract OCR 5.4.1 APIusingJNA Interface Mapping.A Java wrapper forTesseract OCR 5.4.1 APIusingJNA Direct Mapping.An object layer on top ofTessAPI, provides character recognition support for common image formats, and multi-page TIFF images beyond the uncompressed, binary TIFF format supported by Tesseract OCR engine.An object layer on top ofTessAPI1, provides character recognition support for common image formats, and multi-page TIFF images beyond the uncompressed, binary TIFF format supported by Tesseract OCR engine.Encapsulates Tesseract OCR results at certain page iterator level.
