Are the JBIG2 and JPX plugins in your classpaths? Did you see any log
messages? Did you activate logging?

The attached pdf is the first page referred to in this link from Gunnar Brand.

When I render this page in pdfbox 2.0.24 I get a blank page using code similar
to below, which works for documents which are not using masks.
PDDocument document = PDDocument.load(fileAsByteArray)
PDFRenderer renderer =new PDFRenderer(document);
// configuring renderer for best image RenderingHints hints =new
RenderingHints(null);
hints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_SPEED);
hints.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_OFF);
hints.put(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
renderer.setRenderingHints(hints);
// render relevant the pages into memory BufferedImage bufferedImage =
renderer.renderImage(0,5, ImageType.BINARY);
I have tried with/without the hints and with different scales and image types.
Any ideas what's going wrong here?
Thanks.
