Hello,
I'm trying to use PDFBox to extract a page from a multi page document
and creating a new document from it. I thought it would be as simple
as getting the PDPage, get contents..then create a new PDPage, set
content, and add it to a new PDDocument...but I guess it's not that
straight forward, or I'm missing something.
If I extract a PDPage, and put that same PDPAge it in a new document
and save it, it works.
i.e.
InputStream fileStream =
this.getClass().getResourceAsStream("sample.pdf");
PDDocument document = PDDocument.load(fileStream);
PDPage pdfPage = (PDPage) document.getDocumentCatalog().getAllPages().get(0);
PDDocument document2 = new PDDocument();
document2.addPage(pdfPage);
document2.save("c:\\generatedPDF.pdf");
document2.close();
But if I take the PDPage content and create a new PDPage, it doesn't work.
InputStream fileStream =
this.getClass().getResourceAsStream("sample.pdf");
PDDocument document = PDDocument.load(fileStream);
PDPage pdfPage = (PDPage) document.getDocumentCatalog().getAllPages().get(0);
PDDocument document2 = new PDDocument();
PDPage testPDPage = new PDPage();
testPDPage.setContents(pdfPage.getContents());
document2.addPage(testPDPage);
document2.save("c:\\generatedPDF.pdf");
document2.close();
At the end of the day, what I'm trying to do is extract all the pages
from the document, store it in a database, retrieve each page sometime
in the future and create a document with that one page. So, at some
point I figure I'll be converting the contents inty a bytearray and
store that, and recreate it.
Any help would be appreciated. Thanks for your time.
