Daniel Persson commented on PDFBOX-5170:
----------------------------------------
Hi [~mkl]
I can verify that your fix solves the issue. Another thing that might be
related when reading the specification about Cross-Reference Stream (new
knowledge for me) is that they may not be encrypted and need a different flag
if compressed.
But do I understand the specification correctly that this is extra information
for performance and not required to present the document correctly?
Best regards
Daniel

> Hi Team.
>
> PDFBox version 3.0.0-RC1
> pdftoppm version 21.04.0
> mupdf-gl version 1.18.0
>
> This might be an unusual issue but might needs to be checked. The simple code
> below creates a PDF that can't be viewed with Poppler because of "error:
> malformed page tree"
> {code:java}
> PDDocument testPdf = Loader.loadPDF(new File("input.pdf"));
> testPdf.save(new File("output.pdf"));
> testPdf.close();
> PDDocument testPdf2 = Loader.loadPDF(new File("input.pdf"));
> testPdf2.save(new File("output2.pdf"), CompressParameters.NO_COMPRESSION);
> testPdf2.close();
> {code}
> This is not a content issue because all PDFs from the same producer have the
> same problem, I've just picked an example.
> Best regards
> Daniel
