#Chrome pdf signature pdf#
The following code sample will sign a pdf document using a local certificate and place some text into the SignatureAppearance which is not shown in chrome. !AkROTDoCWFJnkd5W5P3MCbb8fwLASA?e=zsmks0.Pdf which doesn't show signature in chrome.
!AkROTDoCWFJnkd5VOFjUHZfpQXzJWQ?e=MeyZje.If i open the first pdf in chrome, the signature appearance text is not shown, but if i open the pdf which was initially created using word, the signature apperance is missing.Īny ideas on whats wrong with the pdf which doesn't show the signature appearance in chrome? edit: Links to the documents The second image is a demo pdf i just downloaded random. The first image is a pdf created using word and the save as pdf functionality.
The produced pdf shows this appearance if i open it using adobe reader.
This is described in the digital signature book chapter 2.4 Creating different signature appearances. In addition to the digital signature, i want to show a visual representation on the pdf. This works without problems, and the signature is shown as valid. I am using iText 7 to sign pdf documents.
