PDFNEWJAVA-33678 Converting non searchable PDF to searchable PDF document

This feature is implemented.

This logic recognize text for pdf images. For recognition you may use outer OCR supports HOCR standard(http://en.wikipedia.org/wiki/HOCR).
 I have used free google tesseract OCR(http://en.wikipedia.org/wiki/Tesseract_%28software%29)
 Please install it to you computer from http://code.google.com/p/tesseract-ocr/downloads/list, after that you will have tesseract.exe console application.
 To inspect result Pdf visually, open the result output971.pdf in Adobe Reader and press Ctrl+A to select all the text.
 
Example:

initLicense();
	final String myDir = "D:\\LocalTesting\\";
	Document doc = new Document(myDir + "input.pdf");
	// Create callBack - logic recognize text for pdf images. Use outer OCR supports HOCR standard(http://en.wikipedia.org/wiki/HOCR).
	// We have used free google tesseract OCR(http://en.wikipedia.org/wiki/Tesseract_%28software%29)
