ErrorCode: 4000; Error Message: "Unrecognized PDF content" displayed in PDF/SigQ conformance report dialog box under View Document Integrity properties button under Legal Tab as shown in Attached image

Hi,

Thanks to Aiken Sam and Paulo for providing the Timestamp example for signing the pdf. I am using the itext 1.4.4 version, java 1.4.2, bouncy castle API for java 1.4.2 and  TSA server as adobe-timestamp.geotrust.com/tsa.

I am using the same example as posted at the following location and able to generate the pdf:

http://www.nabble.com/PDF-Digital-signature-with-timestamp---using-Time-Stamp-Authority---example-t4147508.html

On opening the pdf, it shows the blue ribbon and says that The document was certified by <[e-mail]>, company with the valid certificate issued by GeoTrust CA for adobe. I am able to see the following message as well on clicking the Signature properties button:

1. The document has not been modified since it wa modified.
2. the signer identity is valid.
3. Signature is timestamped.

But when i am going to Legal Tab and clicking the View Document Integrity properties button, then in the PDF/SigQ conformance report dialog box. I am getting the error message as:

" 4000 Unrecognized PDF content. "
Unrecognized PDF content: The document contains PDF content or custom content not supported by the current version of Adobe Reader.

The document contain rich content that cannot be reliably suppressed. contact the document author regarding whether you should sign or trust the signature in this document.

Please see the above error in the attached image file.

What i can think of that i have an image in gif format as a logo in the PDF. So, is that creating the problem?  OR something else. I tried to search on google but didin't find anything useful.

Any help or pointer towards resolution will be helpful. Thanks in advance for help.

Thanks
