>
> A PDF document contains Signature fields (X.509) with /SigFlags 1 indication in the /Catalog object.
> When the document is flattened, this signature image remains in the document and underlying object is removed. Perfect!
> But the SigFlags in /Catalog object is not removed although this has no value anymore and prevent the document being correct signed/certifiied afterwards (at least with our software).
> Can the SigFlags in /Catalog object be removed or its value be changed to 0 so this corresponds to the content of the document ?
