Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites in place:

1. Install GroupDocs.Comparison for .NET

Ensure that you have GroupDocs.Comparison for .NET installed in your development environment. You can download the necessary files from the download link.

2. Obtain a License

To utilize GroupDocs.Comparison for .NET, you’ll need a valid license. You can either purchase a license from GroupDocs or obtain a temporary license for evaluation purposes from here.

3. Familiarity with .NET Development

Basic knowledge of .NET programming is required to follow along with this tutorial.

Import Namespaces

Before proceeding with the comparison process, ensure you import the necessary namespaces into your .NET project.

using System;
using System.IO;
using GroupDocs.Comparison;
using GroupDocs.Comparison.Options;

Step 1: Define Output Directory and File Name

Firstly, specify the directory where you want to store the comparison result and the name of the output file.

string outputDirectory = "Your Document Directory";
string outputFileName = Path.Combine(outputDirectory, "RESULT.png");

Step 2: Initialize Comparer

Next, initialize the Comparer object by providing the source image stream.

using (Comparer comparer = new Comparer(File.OpenRead("SOURCE.png")))
{

Step 3: Add Target Image

Add the target image to the comparison process by providing its stream.

comparer.Add(File.OpenRead("TARGET.png"));

Step 4: Configure Comparison Options

Configure the options for image comparison. In this example, we set GenerateSummaryPage to false to prevent generating a summary page.

CompareOptions options = new CompareOptions();
options.GenerateSummaryPage = false;

Step 5: Perform Comparison

Execute the comparison process by calling the Compare method and providing the output file name and comparison options.

comparer.Compare(outputFileName, options);

Step 6: Display Result

Finally, display a message confirming the successful comparison and the location of the output file.

Console.WriteLine($"\nImages compared successfully.\nCheck output in {Directory.GetCurrentDirectory()}.");
