Implementation Guide

With everything set up, let’s add watermarks to diagrams using GroupDocs.Watermark for .NET.

Adding Watermarks to Diagrams with Separate Background Pages

This feature allows adding text watermarks to diagram background pages. Here’s how:

Step 1: Initialize the Watermarker Object

Load your document and initialize a Watermarker object.

string documentPath = "YOUR_DOCUMENT_DIRECTORY"; // Replace with your file path
string outputDirectory = "YOUR_OUTPUT_DIRECTORY"; // Replace with your output directory path
string outputFileName = Path.Combine(outputDirectory, Path.GetFileName(documentPath));
DiagramLoadOptions loadOptions = new DiagramLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Further steps will go here...
}

Step 2: Create a Text Watermark

Define the watermark text and style.

TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Calibri", 19));

Here, “Test watermark” is displayed in Calibri font at size 19 points.

Step 3: Configure Watermark Options

Specify where the watermark should be placed on the diagram:

DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
options.PlacementType = DiagramWatermarkPlacementType.SeparateBackgrounds; // Target separate backgrounds

Step 4: Add and Save the Watermark

Add your watermark using defined parameters, then save the file.

watermarker.Add(textWatermark, options);
watermarker.Save(outputFileName);

This step saves the modified file in the specified output directory.

Troubleshooting Tips

  • File Path Issues: Ensure correct paths for documentPath and outputDirectory.
  • Library Compatibility: Verify compatibility with your .NET framework version.
