Add Tiled Image Watermark

Introduction

GroupDocs.Watermark for .NET is a powerful API that allows developers to add, remove, and search watermarks in various document formats programmatically. In this tutorial, we will guide you through the process of adding a tiled image watermark to your documents using GroupDocs.Watermark for .NET.

Prerequisites

Before you begin, ensure you have the following:

• Basic knowledge of C# programming language.
• Visual Studio installed on your system.
• GroupDocs.Watermark for .NET library added to your project. You can download it from here.

Import Namespaces

Make sure to import the necessary namespaces at the beginning of your C# file:

using GroupDocs.Watermark.Watermarks;
using System;
using System.IO;

Step 1: Set Document Path and Output Directory

Define the path of your input document and the directory where you want to save the output document:

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

Replace "Your Document Path" with the absolute or relative path to your input document.

Step 2: Initialize Watermarker Object

Create a Watermarker object using the input document path:

using (Watermarker watermarker = new Watermarker(documentPath))
{
    // Add watermark here
}

Step 3: Add Tiled Image Watermark

Instantiate an ImageWatermark object with the path to the image file you want to use as a watermark:

using (ImageWatermark watermark = new ImageWatermark("Path to Your Image"))
{
    // Configure tile options
    watermark.TileOptions = new TileOptions()
    {
        TileType = TileType.Offset,
        LineSpacing = new MeasureValue()
        {
            MeasureType = TileMeasureType.Percent,
            Value = 12
        },
        WatermarkSpacing = new MeasureValue()
        {
            MeasureType = TileMeasureType.Percent,
            Value = 10
        },
    };
    watermark.RotateAngle = -30;
    // Add watermark to the document
    watermarker.Add(watermark);
    // Save the modified document
    watermarker.Save(outputFileName);
}

Replace "Path to Your Image" with the actual path to your watermark image file.

Conclusion
