Examples of WVTInputFilter

edu.udo.cs.wvtool.generic.inputfilter.WVTInputFilter
This interface represents a mechanism, which converts content given by an input stream to a stream of characters. (e.g. a PDF file to plain text). In most cases, the intention is to get plain natural text from this processing step. @author Michael Wurst @version $Id: WVTInputFilter.java,v 1.3 2007/05/20 18:06:04 mjwurst Exp $
