-------------------------------------------
Summary: Not correct support of incremental save
Key: PDFBOX-2981
URL: https://issues.apache.org/jira/browse/PDFBOX-2981
Project: PDFBox
Issue Type: Bug
Components: Writing
Affects Versions: 2.0.0
Reporter: Evgeniy Muravitskiy
When write code like follows:
{code}
try {
PDDocument document = PDDocument.load(new
File(SOURCE_PATH));
// SOME_OBJECT is not object number of catalog, info
dictionary or encrypt
COSObjectKey key = new COSObjectKey(SOME_OBJECT, 0);
COSObject objectFromPool =
document.getDocument().getObjectFromPool(key);
COSDictionary object = (COSDictionary)
objectFromPool.getObject();
object.setItem(COSName.getPDFName("Test"),
COSBoolean.TRUE);
object.setNeedToBeUpdated(true);
OutputStream writer = new BufferedOutputStream(new
FileOutputStream(OUTPUT_PATH));
document.saveIncremental(writer);
writer.close();
document.close();
} catch (IOException e) {
e.printStackTrace();
}
{code}
in result file I`ve got nothing. It`s related with next problem: when we use
{{PDDocument.save(OutputStream)}} - {{OutputStream}} is real output stream (for
example, {{FileOutputStream}} or {{BufferedOutputStream}}), but incremental
save use {{ByteArrayOutputStream}} which not store data in some file and only
keep it in memory. Also when save is incremental data from source file is not
send to result file.
