Hi,

Thank you for considering Aspose.

Yes, the stamp's "opacity" can be set throught Aspose.Pdf.Kit, as the sample codes below does. we treat the "opacity" as a property of watermark or background.

stamp = new Stamp();

//stamp.BindImage(imageFile); // for image

stamp.BindLogo(new FormattedText(...)); // for text
stamp.Opacity = 0.5f; // set opacity
stamp.IsBackground = false;
stamp.SetOrigin(75, 10);
PdfFileStamp filestamp = new PdfFileStamp(In_Pdf, Out_Pdf);
filestamp.AddStamp(stamp);
filestamp.Close();

Thanks,
