PDF Version

Hi,

the PDF Version is just a number and it should reflect the minimum version which the reader must support. 1.4 is very common and the basis of PDF/A. There should be no difference for any signing process - the signing is applied on top of the PDF, after the creation. The complete file is hased in placed inside of a kind of wrapper. I would say, this info of the customer is not correct.

Of course we could change the string in the pdf file, but I don't see really a sense for it. It can be also done after the creation by changing byte X.

Hi,

we are creating pdf file with Version 1.4

%PDF-1.4

One of our big customer creates a signature for the pdf, and the pdf-version must be 1.5 or greater!

Is it possible, to create such pdf's?

Thanks,
Patrick
