Is there an easy way to determine if a pdf contains any JBIG2,
JPEG2000 ... images. I mean all image types which are not supported by
plain pdfbox renderer.
It would be sufficient to get that information from the first page.
I know that I could iterate over content objects and but I believe
that this will take some time and will. Any ideas?
You could try to use the ExtractImages.java example but run it only on
the first page, and not extract the image XObects, just check their suffix.
