  2. Access to Word Documents: Have access to the Word documents containing watermarks that you want to manipulate.
  3. Basic Knowledge of C#: Familiarize yourself with C# programming language basics, as this tutorial will involve C# code snippets.

Import Namespaces

Before getting started with the code, import the necessary namespaces:

using GroupDocs.Watermark.Contents;
using GroupDocs.Watermark.Contents.WordProcessing;
using GroupDocs.Watermark.Options.WordProcessing;
using GroupDocs.Watermark.Search;
using GroupDocs.Watermark.Search.SearchCriteria;
using System.IO;
using System;

Step 1: Define Document Path and Output File Name

First, define the path of the document containing the watermark and the output file name where the modified document will be saved.

string documentPath = "Your Document Path";
string outputFileName = Path.Combine("Your Document Directory", Path.GetFileName(documentPath));

Step 2: Initialize Watermarker

Initialize the Watermarker object with the document path and load options.

var loadOptions = new WordProcessingLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Code for watermark manipulation will go here
}

Step 3: Define Search Criteria

Define the search criteria to find the watermark. This can be based on image or text.

ImageSearchCriteria imageSearchCriteria = new ImageDctHashSearchCriteria(Constants.LogoPng);
TextSearchCriteria textSearchCriteria = new TextSearchCriteria("Company Name");

Step 4: Search for Watermarks

Search for watermarks in the primary header of the document using the defined search criteria.

WordProcessingContent content = watermarker.GetContent<WordProcessingContent>();
PossibleWatermarkCollection possibleWatermarks = content.Sections[0]
                                                        .HeadersFooters[OfficeHeaderFooterType.HeaderPrimary]
                                                        .Search(textSearchCriteria.Or(imageSearchCriteria));

Step 5: Remove Watermarks

Remove all found watermarks from the document.

for (int i = possibleWatermarks.Count - 1; i >= 0; i--)
{
    possibleWatermarks.RemoveAt(i);
}

Step 6: Save Document

Save the modified document with removed watermarks.

watermarker.Save(outputFileName);
