Hi,
I'm testing the viewer.
I'm using the GroupDocs.Viewer.WebForm.FrontEnd showcase project.
I've added this line in the ViewDocumentAsHtml method to generate a Watermark
htmlOptions.Watermark = new Watermark("Watermark", Color.Blue, Domain.WatermarkPosition.Diagonal, 100);
When I run the project the document viewer shows the document and the watermark but then the watermark disappears
Can you help me?
