Hi,
I can display it. Did you get a log message like this?
Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools
are not installed
Please read
https://pdfbox.apache.org/2.0/dependencies.html
The link to jai is broken... it's either a file named jai_imageio.jar
that you have somewhere, or
http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html
, or the files from
https://github.com/jai-imageio/jai-imageio-core
https://github.com/jai-imageio/jai-imageio-jpeg2000

Hi,
You posted the same URL twice. So we can see but not the PDF. Please
mention the version you are using (hopefully 2.0.7).

Hi, I am using pdfbox to convert PDF to jpgs.
I have a case that the original PDF has signature but when converted to PDF the
signature is lost.
Is there any special setting for exporting signature?

My code is very simple:
pdfRenderer = new PDFRenderer(document)
pdfRenderer.renderImageWithDPI(page, DPI, ImageType.RGB)
Thanks
