Examples of org.jpedal.PdfDecoder.openPdfArray()

org.jpedal.PdfDecoder.openPdfArray()
routine to open a byte stream containing the PDF file and extract key info from pdf file so we can decode any pages. Does not actually decode the pages themselves - By default files over 16384 bytes are cached to disk but this can be altered by setting PdfFileReader.alwaysCacheInMemory to a maximimum size or -1 (always keep in memory)

          PdfDecoder.setFontReplacements(decodePdf);
          decodePdf.useHiResScreenDisplay(true);
          decodePdf.getDPIFactory().setDpi(2 * 72);
          decodePdf.setPageParameters(1, 1);
          try {
            decodePdf.openPdfArray(baos.toByteArray());
            /** get page 1 as an image */
            BufferedImage img = decodePdf.getPageAsImage(1);


            /** close the pdf file */
            decodePdf.closePdfFile();
