Invoke the Compare method to perform the document comparison and save the result.

comparer.Compare(File.Create(outputFileName));

Step 5: Generate Document Previews

Generate previews of the compared document for visual inspection.

Document document = new Document(File.OpenRead(outputFileName));
PreviewOptions previewOptions = new PreviewOptions(pageNumber =>
{
    var pagePath = Path.Combine(Constants.SamplesPath, $"result_{pageNumber}.png");
    return File.Create(pagePath);
});
previewOptions.PreviewFormat = PreviewFormats.PNG;
previewOptions.PageNumbers = new int[] { 1, 2 };
previewOptions.Height = 1000;
previewOptions.Width = 1000;
document.GeneratePreview(previewOptions);

Step 6: Display Output

Display a success message with the path to the generated document previews.

Console.WriteLine($"\nDocument previews generated successfully.\nCheck output in {outputDirectory}.");
