Hello,
I'm trying to write the same PDF file twice using different Encrypt parameters
(example: different user passwords).
It goes like this :
pdf->SetEncrypted(*encrypt1);
pdf->Write(path1); // Creates the Encrypt object, but references it in a copy
of the trailer, that is deleted after the write is complete
pdf->SetEncrypted(*encrypt2);
pdf->Write(path2); // Creates a second Encrypt object and references it in a
new copy of the trailer, etc..
When I do this, the Encrypt object that was created for the first Write also
appears in the second file, along with the right one (but with no reference to
it). If the file is written many times, the object is then duplicated as many
times.
Question: Is there a reason and is it necessary for the PdfWriter object to
make a copy of the trailer in its constructors ? If it wasn't, we could delete
the Encrypt object every time a new one is set because the reference would be
stored in the PdfDocument Object. I actually tried changing it and it worked
for each of my tests but I haven't tested every case and I don't have the
necessary perspective to know if it could have broken something else somewhere.
Thanks in advance for you answers.
Regards,
