Merging PDF with XFDF not working

Hi, I’m testing the Aspose PDF library and I’m trying to merge a PDF file with an XFDF file (xfdf includes INK Annotations).

Test code (see below) runs without any problems but the output pdf file does not include the annotations!

Any idea how to solve this problem?

Also attached a zip with the pdf and xfdf files.

Aspose.Pdf.License pdflicense = new Aspose.Pdf.License();


pdflicense.Embedded = false;

var annotationEditor = new PdfAnnotationEditor();



var fileStream = new System.IO.FileStream(xfdf, System.IO.FileMode.Open, System.IO.FileAccess.Read);

Enum[] annotType = { AnnotationType.Text, AnnotationType.Ink, AnnotationType.Popup };

annotationEditor.ImportAnnotationFromXfdf(fileStream, annotType);
