Sorry, you cannot use WPViewPDF in WPF, only in WinForms.

License is in royalty free.

Annotations can be changed by direct access to the PDF objects.

This works by reading the XML used internally for the annotation, change certain properties and write it back.

A free text can use XML like this:

Code

?xml version="1.0" encoding="utf-8"?>
<neutral value="###"></neutral>
<annot X="283.07" Y="44.43" W="141.99" H="60.92" prp.n.Subtype="FreeText" Font="Arial" Font-Size="0" _mult="3.28" prp.s.Contents="avyxcvxc"></annot>

The demo uses this code to show an editor and writes back the XML

Code

var s : string;
begin
   if pdf<>nil then
   begin
     s := pdf.CommandGetStr(COMPDF_Ann_XMLGetFromAnnots, '###', 0);
     if ShowPopupEditor('Modify Annotations', s, true) then
     begin
         s := StringReplace(s, #13+#10, #32, [rfReplaceAll]);
         s := StringReplace(s, #10, #32, [rfReplaceAll]);
         pdf.CommandStrEx(COMPDF_Ann_XMLSetToAnnots, s, 0);
     end;
   end;
end;
