Maruan Sahyoun commented on PDFBOX-1533: ---------------------------------------- OK - can you try building pdfbox from trunk or wait for 1.8.1? If not we would need a set of pdfs to reproduce the issue. If trunk or 1.8.1 don't fix it we will also need sample pdfs. > When merging certain PDF's several odd looking empty pages occure in the > result > ------------------------------------------------------------------------------- > > Key: PDFBOX-1533 > URL: https://issues.apache.org/jira/browse/PDFBOX-1533 > Project: PDFBox > Issue Type: Bug > Components: Utilities > Affects Versions: 1.7.1 > Reporter: Christian Connert > > Unfortunately I cannot attach a input file for this case as it contains > confidential customer data, but I'll try to explain the problem in depth so > you hopefully are able to track it down. > When we merg certain PDF's with the PDFMergerUtility the result contains > serveral empty pages at the end of the document. It seems like that only > certain pdf versions are effected (i.p.: 1.5 (Acrobat 6.x)). > I tracked the problem down to the the following part in the appendDocument > method of the PDFMergerUtility: > //finally append the pages > List<PDPage> pages = srcCatalog.getAllPages(); > Iterator<PDPage> pageIter = pages.iterator(); > while( pageIter.hasNext() ) > { > PDPage page = pageIter.next(); > PDPage newPage = > new PDPage( (COSDictionary)cloner.cloneForNewDocument( > page.getCOSDictionary() ) ); > newPage.setCropBox( page.findCropBox() ); > newPage.setMediaBox( page.findMediaBox() ); > newPage.setRotation( page.findRotation() ); > destination.addPage( newPage ); > } > The problem is that call to srcCatalog.getAllPages(); returns for expamle 6 > PDPage objects, but for the same input document, the call to > source.getNumberOfPages() returns only 2. Thus we add 4 odd empty pages to > the result document. > I hope this description is good enought to figure out the problem. Don't > hesitate to ask for further details. -- This message is automatically generated by JIRA.
