xsane2tess3 scans images with TesseractOCR
and outputs the text in a file or as hocr/html document
OPTIONS:
-i <file1> define input file (any image-format supported)
-o <file2> define output-file (*.txt/hOCR)
-l <lang> define language-data tesseract should use
-e <config> filename for tesseract
-f </path/to/Final> name and path fot multiscan document
Progress- & error-messages will be stored in this logfile:
$TEMP_DIR$ERRORLOG
xsane2tess depends on
- XSane, http://www.xsane.org/
- TesseractOCR, http://code.google.com/p/tesseract-ocr/
Some coding was stolen from 'ocube'
http://www.geocities.com/thierryguy/ocube.html
This adaption is based on xsane2tess
