There are no memory optimizations. I have some plans to have it cache to
disk but it's still a long way.

Subject: [iText-questions] Any memory optimizations for PdfCopyFields since
1.3.4
Hello I was wondering if there have been any improvements in memory
management since release 1.3.4. Specifically we are using the PdfCopyFields
object to perform a merge.
Here is a snippet of our code that is doing the merge.
private PdfCopyFields pdfCopyFields = null;
public byte[] generateMergedPdf() throws InterruptedException
{
shutdownOrderedMergeService();
// merge content
byte[] myMergedContent = null;
synchronized (pdfCopyFields)
{
try
{
if (pdfCopyFields != null)
{
if (bookmarkList != null && bookmarkList.size() > 0)
{
pdfCopyFields.setOutlines(bookmarkList);
}
// generate merged document
pdfCopyFields.close();
myMergedContent =
byteArrayOutputStream.toByteArray();
}
}
finally
{
cleanupResources();
}
}
return myMergedContent;
}
We had a couple of users attempting to merge pdf documents totaling 112 meg
in size twice.
Under load (i.e. High memory usage) we see the following exception: We have
upped the process to 1.5 gig of memory. Just wondering if you have made any
memory optimizations to iText that would warrant us to upgrade to the
latest release.
java.lang.RuntimeException: The document is not open.

The date on the class files is 9-22-2005. So assuming we are running with
version 1.3.4
Thanks for any help
