Hello,
I’m trying to copy a page from a PDF and adding it to a new (empty) document
but I’m running into an issue when I close the source PDF file before I save
the destination file.
Here’s a code snippet:
// Load up some document from which to copy a page
PDDocument documentA = PDDocument.load(new File("a.pdf"));
// Create a new document and import the first page of the a document
PDDocument newDocument = new PDDocument();
newDocument.importPage(documentA.getPage(0));
// Close the A document as we don't need it any longer
documentA.close();
// Save the new document, this throws:
// COSStream has been closed and cannot be read. Perhaps its enclosing
PDDocument has been closed?
// java.io.IOException: COSStream has been closed and cannot be read.
Perhaps its enclosing PDDocument has been closed?
newDocument.save(new File("new.pdf"));
I get a similar exception when using the PDFMergerUtility class.
I need to copy quite a few pages into a single output document and I’d like to
avoid keeping all those source documents open both at the source and in the
destination document.
Any ideas?
Kind regards,
Simon
