It seems like for some reason Aspose.Word evaluation injects the watermark text twice so the converted HTML is placed right between the watermarks… Could you please attach or post your code sample? I have the converted pdf looking fine with this snippet of code:
Document doc = new Document(Path.Combine(PATH, “test.html”));
doc.Save("temp.xml", SaveFormat.FormatAsposePdf);
Aspose.Pdf.Pdf pdf = new Aspose.Pdf.Pdf();
pdf.BindXML("temp.xml", null);
pdf.Save(Path.Combine(PATH, "result.pdf"));
Thanks Uwe. Please make sure that you are using the latest version of Aspose.Word and report us if it helps. Anyway, we have logged your request and will try to fix it quickly.
