Add Text Watermark With Specific Options

Introduction

Watermarks can be a stylish and functional addition to your Word documents, serving purposes from marking documents as confidential to adding a personalized touch. In this tutorial, we’ll explore how to add a text watermark to a Word document using Aspose.Words for .NET. We’ll dive into the specific options you can configure, such as font family, font size, color, and layout. By the end, you’ll be able to customize your document’s watermark to fit your exact needs. So, grab your code editor, and let’s get started!

Prerequisites

Before we get rolling, make sure you have the following in place:

  1. Aspose.Words for .NET Library: You’ll need the Aspose.Words library installed. If you haven’t done so already, you can download it from the Aspose.Words Download Link.
  2. Basic Understanding of C#: This tutorial will be using C# as the programming language. A fundamental grasp of C# syntax will be helpful.
  3. .NET Development Environment: Ensure you have a development environment set up (like Visual Studio) where you can create and run your .NET applications.

Import Namespaces

To work with Aspose.Words, you’ll need to include the necessary namespaces in your project. Here’s what you need to import:

using Aspose.Words;
using Aspose.Words.Rendering;
using System.Drawing;

Step 1: Set Up Your Document

First, you need to load the document you want to work with. For this tutorial, we’ll use a sample document named Document.docx. Make sure this document exists in your specified directory.

// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document(dataDir + "Document.docx");

In this step, you define the directory where your document is located and load it into an instance of the Document class.

Step 2: Configure Watermark Options

Next, configure the options for your text watermark. You can customize various aspects, such as font family, font size, color, and layout. Let’s set up these options.

TextWatermarkOptions options = new TextWatermarkOptions()
{
    FontFamily = "Arial",
    FontSize = 36,
    Color = Color.Black,
    Layout = WatermarkLayout.Horizontal,
    IsSemitrasparent = false
};

Here’s what each option does:

  • FontFamily: Specifies the font of the watermark text.
  • FontSize: Sets the size of the watermark text.
  • Color: Defines the color of the watermark text.
  • Layout: Determines the orientation of the watermark (horizontal or diagonal).
  • IsSemitrasparent: Sets whether the watermark is semi-transparent.

Step 3: Add the Watermark Text

Now, apply the watermark to your document using the previously configured options. In this step, you’ll set the watermark text to “Test” and apply the options you defined.

doc.Watermark.SetText("Test", options);

This line of code adds the watermark with the text “Test” to the document, applying the specified options.

Step 4: Save the Document

Finally, save the document with the new watermark applied. You can save it with a new name to avoid overwriting the original document.

doc.Save(dataDir + "WorkWithWatermark.AddTextWatermarkWithSpecificOptions.docx");

This code snippet saves the modified document in the same directory with a new file name.

Conclusion

Adding a text watermark to your Word documents using Aspose.Words for .NET is a straightforward process when you break it down into manageable steps. By following this tutorial, you’ve learned how to configure various watermark options, including font, size, color, layout, and transparency. With these skills, you can now customize your documents to better meet your needs or to include essential information such as confidentiality or branding.
