/**
 * used by JPedal for contants which allow user to set flags

 * This is achived with a PdfDecoder method modifyJPedalParameters(Map values).

 * 
 * How does it work?

 * 

 * The example code below gives examples of how to use this function and a full list of valid settings.
 * It should be called before any files are opened.

 * 
 * Map mapValues=new HashMap();

 * mapValues.put(JPedalSettings.DISPLAY_INVISIBLE_TEXT,Boolean.TRUE);

 * mapValues.put(JPedalSettings.TEXT_HIGHLIGHT_COLOUR, Color.GREEN); 

 * mapValues.put(JPedalSettings.CACHE_LARGE_FONTS,new Integer(65536));

 * //exception will be thrown if invalid value passed

 * PdfDecoder.modifyJPedalParameters(mapValues);
