Alexander Pinske updated PDFBOX-6202:
-------------------------------------
Component/s: PDModel
> Possible regression when combining multiple PDFs
> ------------------------------------------------
>
> Key: PDFBOX-6202
> URL: https://issues.apache.org/jira/browse/PDFBOX-6202
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 3.0.7 PDFBox
> Reporter: Alexander Pinske
> Priority: Major
> Attachments: X1.pdf, X2.pdf, X_actual.pdf, X_expected.pdf
>
>
> Worked in 3.0.6, might be a regression caused by PDFBOX-6036.
> {code:java}
> @Test
> void testPDFBoxX() throws IOException
> {
> try (PDDocument d1 = Loader.loadPDF(new
> RandomAccessReadBuffer(getClass().getResourceAsStream("/input/X1.pdf")));
> PDDocument d2 = Loader.loadPDF(new
> RandomAccessReadBuffer(getClass().getResourceAsStream("/input/X2.pdf")));
> PDDocument d = new PDDocument()) {
> List<PDPage> pages = new ArrayList<>();
> d1.getPages().forEach(pages::add);
> d2.getPages().forEach(pages::add);
> for (PDPage page : pages) {
> d.addPage(page);
> }
> d.save(new FileOutputStream("target/X.pdf"));
> }
> }
> {code}
> It starts working again, when I add this line before the call to addPage:
> {code:java}
> page.getCOSObject().resetImportedObjectKeys();
> {code}
> I do know about importPage, but we are not using that to avoid an extra copy,
> as the source pdfs are discarded after.
