Hello,

Is it possible to add annotation with automatically renewed date value on PDF file page using PDFium.NET?

Here is an example PDF file I'd like to create:
Overlay_with_autodate.pdf (14kb) downloaded 4 time(s).

Hello Paul,

Thank you for this info! Now I'm able to add JavaScript to PDF file (see my code snippet below).

But I need to be able to add PdfWidgetAnnotation, that shows date this Java script calculate. Do you have any idea where can I see code example for this task?

Using doc = PdfDocument.Load(sSrcPDF, New PdfForms())
Dim action = New Actions.PdfJavaScriptAction(doc, "var f = this.getField(""date"");"" & vbCrLf & ""f.value = util.printd(""dd/mmmm/yyyy"",new Date());")

Dim tree = New Wrappers.PdfNameTreeCollection(doc, "JavaScript")
tree.Add("Action_CreateAnnotation", action.Dictionary)
doc.Save(sDstPDF, SaveFlags.NoIncremental)
End Using
