问题:

i want to extract a Stream-Dump from a PDF with PDFBox. Is this possible with PDFBox?

I want to get the original HEX-Code of the Content of a PDF, like this:

For a single use, run PDFDebugger and look for "Contents".

For multiple use, use this code for the first page:

try (PDDocument doc = PDDocument.load(new File("XXX.pdf")); 
        InputStream contents = doc.getPage(0).getContents())
{
    IOUtils.copy(contents, System.out);
}

Note that this will only dump the page content stream. There may be other content streams in xobject forms, patterns, soft masks, annotation appearance streams. PDF is quite complex.
