A good library for converting PDF to TIFF? [closed]

Answer 1

I have some great experience with iText (now, I'm using 5.0.6 version) and this is the code for tiff convertion into pdf:

private static String convertTiff2Pdf(String tiff) {

    // target path PDF
    String pdf = null;

    try {

        pdf = tiff.substring(0, tiff.lastIndexOf('.') + 1) + "pdf";

        // New document A4 standard (LETTER)
        Document document = new Document(PageSize.LETTER, 0, 0, 0, 0);

        PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(pdf));
        int pages = 0;
        document.open();
        PdfContentByte cb = writer.getDirectContent();
        RandomAccessFileOrArray ra = null;
        int comps = 0;
        ra = new RandomAccessFileOrArray(tiff);
        comps = TiffImage.getNumberOfPages(ra);

        // Convertion statement
        for (int c = 0; c < comps; ++c) {
            Image img = TiffImage.getTiffImage(ra, c + 1);
            if (img != null) {
                System.out.println("page " + (c + 1));
                img.scalePercent(7200f / img.getDpiX(), 7200f / img.getDpiY());
                document.setPageSize(new Rectangle(img.getScaledWidth(), img.getScaledHeight()));
                img.setAbsolutePosition(0, 0);
                cb.addImage(img);
                document.newPage();
                ++pages;
            }
        }

        ra.close();
        document.close();

    } catch (Exception e) {
        logger.error("Convert fail");
        logger.debug("", e);
        pdf = null;
    }

    logger.debug("[" + tiff + "] -> [" + pdf + "] OK");
    return pdf;

}
