        final Redactor redactor = new Redactor("Sample.pdf");
        try 
        {
            // Get the actual size information for the last page:
            IDocumentInfo info = redactor.getDocumentInfo();
            PageInfo lastPage = info.getPages().get(info.getPageCount() - 1);
            ReplacementOptions options = new ReplacementOptions("[secret]");
            options.setFilters(new RedactionFilter[] {
                new PageRangeFilter(PageSeekOrigin.End, 0, 1),
                new PageAreaFilter(new java.awt.Point(0, lastPage.getHeight()/2),
                    new java.awt.Dimension(lastPage.getWidth(), lastPage.getHeight()/2))
            });
            RedactorChangeLog result = redactor.apply(new ExactPhraseRedaction("bibliography", false, options));
            if (result.getStatus() != RedactionStatus.Failed)
            {
                redactor.save();
            }                            
        }
        finally { redactor.close(); }
