I tried to scan my PDF file with Multilizer PDF Translator tool (or PDF Scanner) but no strings were found. Is this some bug or I'm missing something?
PDF files can be composed either of text, or of images. In first case usually there shouldn't be any problems with scanning this document. In second case Multilizer won't find anything since there's no text. In this case please try to use some OCR software first and only after that try scanning resulting document in Multilizer.
