Stamp Annotations created with Aspose break if rotated in Adobe Reader

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.

We will surely look into details of this issues. However, can you please also share a sample code snippet that you are actually using to add a stamp annotation in the first place? We will perform investigation accordingly and share the ticket ID with you.

Here is a VS 2022 sample projects to help replicate this issue.

And here is the code :

    private void Button_Click(object sender, RoutedEventArgs e)
        using var doc = new Document();
        using var asposePage = doc.Pages.Add();

        var asposeRect = new Rectangle(20, asposePage.Rect.Height-60, 120, asposePage.Rect.Height-40);

        var stampAnnotation = new StampAnnotation(asposePage, asposeRect);
        stampAnnotation.Name = Guid.NewGuid().ToString();
        stampAnnotation.Popup = new PopupAnnotation(asposePage, asposeRect);

        var image = new FileStream(@"reject.png", FileMode.Open);

        stampAnnotation.Image = image;

        doc.Save(@"cannotrotate.pdf"); // Will not be able to rotate if opened in Adobe Reader

        doc.ExportAnnotationsToXfdf(@"importinadobe.xfdf"); // Same problem if imported in adobe from this file

        // But if you add the "icon" parameter in the xfdf file with any name preceded by # like bellow it works fine
        // <stamp page="0" flags="print" name="dfbcb8ab-7480-4c86-833e-8709b9397bc8" rect="20,782,120,802" icon="#dudule">
