Ignore changes based on similarity percentage for Slides

Starting with version 25.1, we have introduced the ability to set a tolerance percentage for style changes in the Slides format, allowing you to ignore changes that do not exceed the specified percentage. To use this feature, set IgnoreChangeSettings.Ignore in the CompareOptions class to true. To define the percentage, use the IgnoreChangeSettings.IgnorePercent property. Below is a code snippet demonstrating how to use this feature.

using GroupDocs.Comparison;

string sourcePath = @"source.pptx";
string targetPath = @"target.pptx";
string resultPath = @"result.pptx";

using (Comparer comparer = new Comparer(sourcePath))
{
    // Add target document
    comparer.Add(targetPath);

    // Add compare options
    CompareOptions compareOptions = new CompareOptions()
    {
        DetectStyleChanges = true,
        IgnoreChangeSettings = new IgnoreChangeSensitivitySettings { Ignore = true, IgnorePercent = 10 }
    }

    // Compare and save comparison result
    comparer.Compare(resultPath, compareOptions);
}

Disable image comparison in PDF documents

using GroupDocs.Comparison;

string sourcePath = @"source.pdf";
string targetPath = @"target.pdf";
string resultPath = @"result.pdf";

using (Comparer comparer = new Comparer(sourcePath))
{
    // Add target document
    comparer.Add(targetPath);

    // Add compare options
    CompareOptions compareOptions = new CompareOptions()
    {
        DetectStyleChanges = true,
        CompareImagesPdf = true,
        ImagesInheritanceMode = ImagesInheritance.Target
    }

    // Compare and save comparison result
    comparer.Compare(resultPath, compareOptions);
}
