Good morning,
I use the 7.0.109 version of SignoApi in an application.
In this application I have a form with the STImgCtl control (AxSTIMGCTLLib.AxSTImgCtl) in which I go to upload the pdf file to be signed.
Some pdf files are loaded very slowly and once signe [more]

Can you sign a PDF document already signed with another digital signature?
