Update Watermark Text in DOCX Using Java

Watermarks are crucial in document processing, signifying document status, ownership, or confidentiality. The use of a watermark library streamlines the manipulation of watermarks in DOCX files. This article delves into the process of how to update watermark text in DOCX using Java. Watermarks, whether text or images, are visible overlays on documents serving purposes like branding, security, or identification. Modifying watermark text enables dynamic adjustments to document metadata or status. Here are the essential steps to change watermark text in DOCX in Java.

Steps to Update Watermark Text in DOCX Using Java

  1. Set up your IDE to use GroupDocs.Watermark for Java for updating the watermark text
  2. Create an instance of the Watermarker class, specifying the path of the DOCX file as an argument in its constructor
  3. Instantiate the TextSearchCriteria class to locate the watermark within the DOCX file
  4. Use the Watermarker.search method to retrieve a collection of potential watermarks based on the specified search criteria
  5. Iterate through the collection of watermarks and set the new watermark text using the PossibleWatermark.setText
  6. Use the Watermarker.save method to save the modified DOCX document to disk

By either updating document details dynamically or strengthening security measures, this method gives you the ability to effectively handle watermarks in your documents. Integrate this approach into your Java applications to boost their document processing capabilities. This method is versatile, working well with various operating systems like Windows, macOS, and Linux, as long as Java is installed. Below code example shows how to modify text watermark in DOCX using Java.

Code to Update Watermark Text in DOCX Using Java

import com.groupdocs.watermark.Watermarker;
import com.groupdocs.watermark.licenses.License;
import com.groupdocs.watermark.search.PossibleWatermark;
import com.groupdocs.watermark.search.PossibleWatermarkCollection;
import com.groupdocs.watermark.search.TextSearchCriteria;
public class UpdateWatermarkTextinDOCXusingJava {
public static void main(String[] args) {
// Set License to avoid the limitations of Watermark library
License license = new License();
license.setLicense("GroupDocs.Watermark.lic");
// Specify an absolute or relative path to your document.
Watermarker watermarker = new Watermarker("input.docx");
// Search watermark matching a particular text
TextSearchCriteria searchCriteria =
new TextSearchCriteria("Watermark Text", false);
PossibleWatermarkCollection watermarks = watermarker.search(searchCriteria);
for (PossibleWatermark watermark : watermarks)
{
try
{
// Update text
watermark.setText("Modified Watermark Text");
}
catch (Exception e)
{
// Found entity may not support text editing
// Passed argument can have inappropriate value
// Process such cases here
}
}
watermarker.save("output.docx");
watermarker.close();
}
}

In summary, gaining expertise in updating watermark text in DOCX files using Java enables dynamic and efficient document management, improving productivity and adaptability across different operating environments. After setting up the chosen library and making required adjustments to file paths, integrating the provided code into your applications becomes a seamless and efficient process. Well done!
