Implementation Guide

Feature: Search for Watermarks in Word Headers/Footers

This feature allows you to locate specific text and image watermarks within Word document headers or footers efficiently.

Overview of What This Accomplishes

By leveraging GroupDocs.Watermark, we can search and remove unwanted watermarks from your documents, enhancing their presentation quality.

Steps for Implementation:

Step 1: Define Document Paths

Clearly define the paths to your input and output files:

string documentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "YourDocument.docx");
string outputFileName = Path.Combine("YOUR_OUTPUT_DIRECTORY", Path.GetFileName(documentPath));
Step 2: Initialize Watermarker

Create a Watermarker instance to handle your document:

var loadOptions = new WordProcessingLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{
    // Further processing here
}

Why This Matters: Initializing with WordProcessingLoadOptions ensures that the library correctly identifies and processes Word documents.

Step 3: Set Up Search Criteria

Define criteria to identify both text and image-based watermarks:

ImageSearchCriteria imageSearchCriteria = new ImageDctHashSearchCriteria("YOUR_DOCUMENT_DIRECTORY/YourLogo.png");
TextSearchCriteria textSearchCriteria = new TextSearchCriteria("Company Name");

Parameters Explained:

  • ImageDctHashSearchCriteria searches for a specific image watermark.
  • TextSearchCriteria targets specific text strings.
Step 4: Search and Remove Watermarks

Retrieve possible watermarks from the document’s headers and remove them:

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

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

Troubleshooting Tip: If watermarks aren’t found, verify your search criteria and paths.

Step 5: Save the Document

Finally, save the document without unwanted watermarks:

watermarker.Save(outputFileName);
