This tutorial delves into one of its powerful features: replacing text with formatting for XObject in PDFs. By the end of this guide, you’ll be equipped to seamlessly integrate this functionality into your .NET applications.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites:

  1. GroupDocs.Watermark for .NET: Download and install the library from the download link.
  2. Development Environment: Have a suitable development environment set up, preferably Visual Studio or any .NET-compatible IDE.
  3. Document: Prepare the PDF document where you want to replace text with formatting.

Import Namespaces

In your .NET project, ensure you import the necessary namespaces to leverage GroupDocs.Watermark functionalities:

using GroupDocs.Watermark.Contents.Pdf;
using GroupDocs.Watermark.Options.Pdf;
using GroupDocs.Watermark.Watermarks;
using System.IO;
using System;

Step 1: Load the PDF Document

string documentPath = "Your Document Path";
string outputFileName = Path.Combine("Your Document Directory", Path.GetFileName(documentPath));
var loadOptions = new PdfLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))
{

Ensure you replace "Your Document Path" with the path to your PDF file and specify the output directory for the modified document.

Step 2: Access PDF Content

    PdfContent pdfContent = watermarker.GetContent<PdfContent>();
    foreach (PdfXObject xObject in pdfContent.Pages[0].XObjects)
    {

Utilize the GetContent<PdfContent>() method to access the content of the PDF document. Iterate through the XObjects of the first page.

Step 3: Replace Text with Formatting

        // Replace text
        if (xObject.Text.Contains("Test"))
        {
            xObject.FormattedTextFragments.Clear();
            xObject.FormattedTextFragments.Add("Passed", new Font("Calibri", 19, FontStyle.Bold), Color.Red, Color.Aqua);
        }

Check if the XObject contains the text you want to replace. If found, clear existing text fragments and add new formatted text.

Step 4: Save the Document

    // Save document
    watermarker.Save(outputFileName);
}

Save the modified document to the specified output directory.
