Class Tesseract1

java.lang.Object

net.sourceforge.tess4j.TessAPI1

net.sourceforge.tess4j.Tesseract1

All Implemented Interfaces:

com.sun.jna.Library, ITessAPI, ITesseract

public class Tesseract1
extends TessAPI1
implements ITesseract

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. The extended capabilities are provided by the Java Advanced Imaging Image I/O Tools.

Support for PDF documents is available through PDFBox.

Any program that uses the library will need to ensure that the required libraries (the .jar files for jna and jai-imageio) are in its compile and run-time classpath.
