André Heuner updated PDFBOX-3612:
---------------------------------
Description:
I'd like to add a watermark to a PDF and have the following code:
{code:java}
@Test
public void testAddWatermark() {
try {
for (int n = 0; n < 10; n++) { // test runs well with n
< 3; with n < 10 and w/o overlay.close() warnings are shown
PDDocument pdfDocument = PDDocument.load(new
File("C:\\data\\somePdfFile.pdf"));
PDDocument pdfCopy = Pdf.extract(pdfDocument, 1, 1);
PDDocument watermarkCopy =
Pdf.addWatermark(pdfCopy);
ByteArrayOutputStream byteArrayOutputStream = new
ByteArrayOutputStream();
// save as bytes; exception in comment thrown here
if overlay.close() is called
watermarkCopy.save(byteArrayOutputStream);
byteArrayOutputStream.close();
watermarkCopy.close();
pdfCopy.close();
pdfDocument.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
....
public static PDDocument addWatermark(PDDocument document) {
try {
HashMap<Integer, String> overlayGuide = new HashMap<Integer,
String>();
for(int no = 0; no < document.getNumberOfPages(); no++) {
overlayGuide.put(no +1, "C:\\data\\watermark.pdf");
}
Overlay overlay = new Overlay();
overlay.setInputPDF(document);
overlay.setOverlayPosition(Overlay.Position.FOREGROUND);
PDDocument result = overlay.overlay(overlayGuide);
// overlay.close();
return result;
} catch (Exception e) {
log.error("Error while adding watermark: " +e.getMessage(), e);
return document;
}
}{code}
overlay.overlay(...) seems to cause lot's of warnings:
{code}

Is there anything, that can be done to fix this issue? I tried to close
anything that is closable - but the issue remains. Or can it safely be ignored?
