You can add a watermark to a PDF using the AnnBatesStamp class. Here is some code and documentation that demonstrates this. static void AddWatermarktoFile() { string _sourceFile = @"C:\LEADTOOLS22\Resources\Images\input.pdf"; //Create AnnBatesStampComposer instance and add the created Bates stamp to it using (AnnBatesStampComposer batesStampComposer = new AnnBatesStampComposer()) { //Set the rendering engine AnnBatesStampComposer.RenderingEngine = new AnnWinFormsRenderingEngine(); //Create Bates stamp container, set its size and mapper and attach it to the composer AnnContainer batesStampContainer = new AnnContainer(); //Create AnnBatesStamp and set its properties AnnBatesStamp batesStamp = new AnnBatesStamp(); batesStamp.Font = new AnnFont("Arial", 12); batesStamp.Foreground = AnnSolidColorBrush.Create("Red"); batesStamp.HorizontalAlignment = AnnHorizontalAlignment.Center; batesStamp.VerticalAlignment = AnnVerticalAlignment.Center; batesStamp.Logo.Angle = 45; batesStamp.Logo.Font = new AnnFont("Arial", 32); batesStamp.Logo.Opacity = 0.25; batesStamp.Logo.StretchLogo = true; batesStamp.Logo.Text = "Watermark"; using (RasterCodecs _codecs = new RasterCodecs()) { using (CodecsImageInfo info = _codecs.GetInformation(_sourceFile, true)) { batesStampContainer.Mapper.MapResolutions(info.XResolution, info.YResolution, info.XResolution, info.YResolution); batesStampContainer.Size = batesStampContainer.Mapper.SizeToContainerCoordinates(LeadSizeD.Create(info.Width, info.Height)); batesStampComposer.Stamps.Add(batesStamp); //Apply Bates Stamp to our container batesStampComposer.TargetContainers.Add(batesStampContainer); int pages = _codecs.GetTotalPages(_sourceFile); for (int i = 1; i https://www.leadtools.com/help/sdk/dh/abs/annbatesstamp.html https://www.leadtools.com/help/sdk/tutorials/dotnet-console-add-watermark-to-multipage-file.html
