Water Mark on Word Document

You can use LEADTOOLS Document SDK technology in your application.

You can leverage the AnnBatesStampComposer class, to add a watermark, then use the AnnRenderingEngine to burn the watermark to the image. Since you are wanting to add a watermark to a DOCX file, you will need to use the DocumentConverter class to convert the image with the watermark to DOCX.

Here is some sample code:

string docxFile = @"INPUT DOCX FILE PATH";
string tempFile = @"TEMP FILE PATH FOR IMAGE";
using (RasterCodecs codecs = new RasterCodecs())
{
CodecsImageInfo _info = codecs.GetInformation(docxFile, true);
for (int i = 1; i <= _info.TotalPages; i++)
{
using (RasterImage _image = codecs.Load(docxFile, i))
{
// Set the rendering engine
AnnBatesStampComposer.RenderingEngine = new AnnWinFormsRenderingEngine();
// Create AnnBatesStampComposer instance and add the created Bates stamp to it
AnnBatesStampComposer batesStampComposer = new AnnBatesStampComposer();
//Create Bates stamp container, set its size and mapper and attach it to the composer
AnnContainer batesStampContainer = new AnnContainer();
batesStampContainer.Mapper.MapResolutions(_image.XResolution, _image.YResolution, _image.XResolution, _image.YResolution);
batesStampContainer.Size = batesStampContainer.Mapper.SizeToContainerCoordinates(LeadSizeD.Create(_image.Width, _image.Height));
//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 = 0.5;
batesStamp.Logo.StretchLogo = true;
batesStamp.Logo.Text = "Watermark";
batesStampComposer.Stamps.Add(batesStamp);
//Apply Bates Stamp to our container
batesStampComposer.TargetContainers.Add(batesStampContainer);
RasterImage _burnedImage = AnnBatesStampComposer.RenderingEngine.RenderOnImage(batesStampContainer, _image);
codecs.Save(_image, tempFile, RasterImageFormat.Tif, 24, 1, -1, 1, CodecsSavePageMode.Append);
}
}
using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
using (DocumentConverter docConverter = new DocumentConverter())
{
ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS21\Bin\Common\OcrLEADRuntime");
docConverter.SetOcrEngineInstance(ocrEngine, false);
DocumentConverterJobData jobData = DocumentConverterJobs.CreateJobData(tempFile, @"OUTPUT DOCX FILE PATH", Leadtools.Document.Writer.DocumentFormat.Docx);
DocumentConverterJob job = docConverter.Jobs.CreateJob(jobData);
docConverter.Jobs.RunJob(job);
if (job.Errors.Count > 0)
foreach (var error in job.Errors)
Console.WriteLine($"Error during conversion: {error.Error.Message}\n");
else
Console.WriteLine("Successfully Converted!");
}
}

did you tried this one

Document document = new Document();
document.LoadFromFile(@"E:\work\Documents\New Zealand.docx");

//Insert Text Watermark and Set Format
TextWatermark TXTWatermark = new TextWatermark();
TXTWatermark.Text = "NZ Brief Introduction ";
TXTWatermark.FontSize = 45;
TXTWatermark.FontName = "Broadway BT";
TXTWatermark.Layout = WatermarkLayout.Diagonal;
TXTWatermark.Color = Color.Purple;
document.Watermark = TXTWatermark;

//Save and Launch
document.SaveToFile("TXTWatermark.docx", FileFormat.Docx);
3
System.Diagnostics.Process.Start("TXTWatermark.docx");
