Paulo,
Solved ! But still 1 question remaining (see below)
FYI:
The problem was appearing when an annotation had associated stream.
1- The annotation is stored into an FDF file
The PRStream was instantiated with offset / length, but no content
(bytes member remained null)
2- I create a pdfstamper, using the PDF file as reader
3- When copying the stream, I was using the constructor PRStream(PRStream
stream, PdfDictionary newDic).
When saving, the PDF file was used to retrieve the content rather than
the original FDF file
To fix it:
3- When copying the stream, I am now using the PdfReader.getStreamByte () as
follows:
/**
* The method copies a stream
* @param srcStream if the source stream
* @return a copied stream
*/
protected PdfStream copyStream (PRStream srcStream)
throws IOException
{
PRStream destStream = null;
byte buf[] = srcStream.getBytes ();
if (null == buf)
{
// Should read the content of source stream...
RandomAccessFileOrArray raf =
srcStream.getReader().getSafeFile ();
buf = PdfReader.getStreamBytes (srcStream, raf);
destStream = new PRStream (srcStream.getReader(), buf);
}
else
destStream = new PRStream (srcStream, null);
Iterator srcIt = srcStream.getKeys().iterator ();
while (srcIt.hasNext ())
{
PdfName key = (PdfName) srcIt.next();
PdfObject value = srcStream.get(key);
destStream.put (key, copyObject (value));
}
return destStream;
}
Q1: I noticed the original size of the stream was 2133 with /FlatDecode
filter.
The buffer was then decoded using PdfReader.FlateDecode () (length
5852)
The buffer is then zipped in the PRStream constructor
(Document.compress = true)
The buffer size is then 2130.
So question is: Is this acceptable / normal ?
(Special thank goes to Paulo for his kindness at quickly helping),
Regards,

Yes they are.

PdfStamper is the class to use.

Not a problem but depends exactly on the specific annotation. In general the
indirect reference is created first and is attributed to each dic.
