If I create a stamp annotation with Aspose then open the document and try to rotate the stamp in Adobe Reader, the layout of the annotation is broken and replaced by a black cross. (See the attached PNG)
What I have found is if I export this annotation in xfdf and try to import it in Adobe Reader with the “Import Data File…” feature I have the exact same behavior. (attached “broken.xfdf” in xfdf zip )
However, I can fix this xfdf file simply by adding the “icon” property in the stamp tag. I can put anything as an icon name as long as it is preceded by the # character. I have put icon="#JohnDoe" in the fixed.xfdf file and it work.
Unfortunately, If I use Aspose to read the fixed xfdf file and add stamps to my doc, I am back to the same bad behavior in Adobe Reader when I try to rotate. So it is just a useless workaround for me.
I hope this information can help you to fix this annoying issue.
