I have a pdf with a transparent gif in it.
When I set encryption with
Writer.setEncryption(null, null, PdfWriter.ALLOW_PRINTING |
PdfWriter.ALLOW_COPY, PdfWriter.STANDARD_ENCRYPTION_128);
the gif is showing with wrong colors.

Hi,
We are facing some issues related to Encryption options for PDF documents.
If we apply the option "Allow contents to be modified" or "Change the
Document", then automatically "Document Assembly" will be allowed, but we
did not explicitly apply the "document assembly" setting.
Is it right tha

I'm using iText to encrypt PDF documents. The problem I'm running into is that
the metadata seems to be encrypted as well. I know Acrobat 6 and later can
encrypt a PDF's contents without encrypting the metadata. Does iText support

Hi Shashi,
you're on the right path.
