Its unctional cover is very large. I have not used its signing functionalities though. Possibly not worth the cost just for PDF signing for sure. But it may be worth investigating if you need a lot in terms of windows-platform centric pdf-mangling.

Thank you, Daniel.

I don't think Chilkat's PDF class will ever come close to the QuickPDF library in terms of functionalities, and I considered it (QuickPDF, that is) also because of the signing. I don't think, however, that it supports HSM or smartcard signing, which is my main interest, in this particular.
