How to mark the watermark transparent on the document?

Aspose.Pdf.FloatingBox watermark1 = new Aspose.Pdf.FloatingBox(500,500);

watermark1.BoxHorizontalPositioning = BoxHorizontalPositioningType.Page;

watermark1.BoxHorizontalAlignment = BoxHorizontalAlignmentType.Center;

watermark1.BoxVerticalPositioning = BoxVerticalPositioningType.Page;

watermark1.BoxVerticalAlignment = BoxVerticalAlignmentType.Center;

I tried all of the sample code but still unable to find a way to set the watermark transparent.

Can you please provide some sample code for this? Thanks.

Thanks for considering Aspose.
