There are different modes how to use this Program:

1. OCR mode: has 4 parameters: lang (-DEU/-ENG), mode (-OCR/-READ/-AUTO), infile (PDF/BMP/TIF/PNG) and outfile (TXT)

   • OCR : using tesseract for character recognition
   • READ : using pdfbox to extract text from "text-based" PDF files
   • AUTO : tries to extract text with pdfbox and fallback to tesseract if it is not a text-based PDF file

2. WhiteOnWhite Overlay mode: has 5 parameters: mode (-OVERLAY), infile (PDF), outfile (PDF), text (String) and color (Color.WHITE/Color.BLACK) The overlay text is written on every page of the original document, the original is not changed
