Hi,

I am using GroupDocs.Comparison for .NET to compare PDF files. The comparison results in the output PDF are messed up. Would you please check?

Input and output files are attached.

using (Comparer comparer = new Comparer(filePath1))
{
    comparer.Add(filePath2);
    comparer.Compare(resultFile);
}
