COSStream has been closed exception on simple copy
I am using PDFBox 2.0.24. I am attempting to copy a PDF file to a new
PDDocument and save that new document. The eventual goal is to use Overlay
to overlay various images onto pages of the old document before
adding them to the new document.
The problem I'm having is that when I close the old document or any
intermediary document (like one created when making the Overlay), I get an
error "COSStream has been closed and cannot be read" when I save the new
document.
I can demonstrate this error simply with just a simple function:
@Test
*public* *void* testCopyAnnotation() *throws* Exception {
File inPdfFile = *new* File(*this*.getClass().getResource(
"/patent-3_139_857.pdf").toURI());
PDDocument inDocument = PDDocument.*load*(inPdfFile);
PDDocument outDocument = *new* PDDocument();
*int* pages = inDocument.getNumberOfPages();
*for* (*int* page = 0; page < pages; page++) {
PDPage pdPage = inDocument.getPage(page);
outDocument.importPage(pdPage);
}
inDocument.close();
outDocument.save(*OUT_DIR* + "/out-pdf-patente.pdf");
outDocument.close();
Assert.*assertTrue*(*true*);
}
The stack trace below is triggered by the line "outDocument.save(*OUT_DIR*
+ "/out-pdf-patente.pdf");".
What is wrong here and how might I correct this?
*java.io.IOException*: COSStream has been closed and cannot be read.
Perhaps its enclosing PDDocument has been closed?

Am I seeing this bug? https://issues.apache.org/jira/browse/PDFBOX-3280
If so, I'm not seeing any successful workaround: not with
the PDFCloneUtility, not with
"importedPage.setResources(pdPage.getResources())", nor with a combination
of the two.
Might 3.0.0-alpha2 have a solution?

Re: COSStream has been closed exception on simple copy
Posted by Thad Humphries <th...@gmail.com>.
I seem to have a workaround. The solution is that when a PDF page has
markup, use PDFRenderer to create a BufferedImage of the page at 300dpi,
add the markup to the image (adjusting the markup to 300dpi), add the image
to a new PDpage, and add that new page to outDocument. If there is no
markup, I just add the inDocument PDPage to outDocument.
There's a time-image quality tradeoff, but I don't know if working Overlay
would be faster. 300dpi seems to be good enough for my purposes.

Re: COSStream has been closed exception on simple copy
Posted by Thad Humphries <th...@gmail.com>.
Yes, I can do that. It was meant as a simple illustration. The problem
returns when there are intermediate PDDocuments inside the for-loop
I must create intermediary PDDocuments in order to Overlay a BufferedImage
onto each page. Even that can work if the overlay is the same for each page
*and* I don't close the overlay in the for-loop. But in my case the image
will change with each page.
So this function works:
@Test
*public* *void* testCopyAnnotationOverlay() *throws* Exception {
File inPdfFile = *new* File(*this*.getClass().getResource(
"/patent-3_139_857.pdf").toURI());
PDDocument inDocument = PDDocument.*load*(inPdfFile);
BufferedImage imageOverlay = ImageIO.*read*(*new* File(*this*
.getClass().getResource("/sample-annotation.png").toURI()));
PDDocument outDocument = *new* PDDocument();
*int* pages = inDocument.getNumberOfPages();
PDDocument overlayDocument;
*for* (*int* page = 0; page < pages; page++) {
PDPage pdPage = inDocument.getPage(page);
// Draw an image into a PDF page.
PDPage imagePage = *new* PDPage(pdPage.getCropBox());
PDDocument imageDocument = *new* PDDocument();
imageDocument.addPage(imagePage);
PDPageContentStream cos = *new* PDPageContentStream(imageDocument,
imagePage);
PDImageXObject ximage = LosslessFactory.*createFromImage*(
imageDocument, imageOverlay);
cos.drawImage(ximage, 0, 0);
cos.close(); // this also close imageDocument
overlayDocument = *new* PDDocument();
overlayDocument.addPage(pdPage);
Overlay overlay = *new* Overlay();
overlay.setInputPDF(overlayDocument);
overlay.setOverlayPosition(Overlay.Position.*FOREGROUND*);
overlay.setAllPagesOverlayPDF(imageDocument);
HashMap<Integer, String> overlayProps = *new* HashMap<Integer,
String>();
overlay.overlay(overlayProps);
outDocument.importPage(overlayDocument.getPage(0));
// overlay.close();
}
outDocument.save(*OUT_DIR* + "/out-pdf-patent.pdf");
inDocument.close();
outDocument.close();
Assert.*assertTrue*(*true*);
}
Note the commented out "overlay.close()". Leave that in and there will be a
COSStream error on save(). (Let the JVM clean it up.)
Now alter the function so that "imageOverlay" is created inside the
for-loop (because I'll have a different markup on each page). There will be
a COSStream error on save(), even if I also comment out "cos.close()".
