        try 
        {
            java.util.regex.Pattern rx = java.util.regex.Pattern.compile("urna");
            ReplacementOptions optionsText = new ReplacementOptions("[redarea]");
            optionsText.setFilters(new RedactionFilter[] {
                new PageRangeFilter(PageSeekOrigin.End, 0, 1), // last page
                new PageAreaFilter(new java.awt.Point(300, 0), new java.awt.Dimension(300, 840)) // right half of the page
            });
            RegionReplacementOptions optionsImg = new RegionReplacementOptions(java.awt.Color.RED, new java.awt.Dimension(100, 100));
            RedactorChangeLog result = redactor.apply(new PageAreaRedaction(rx, optionsText, optionsImg));
            if (result.getStatus() != RedactionStatus.Failed)
            {
                redactor.save();
            }
