with the TestLeft-syp I got the object: IDriver driver = new LocalDriver(); IControl image = driver.Find<IProcess>(new ProcessPattern() { ... }, 5).Find<IControl>(new WPFPattern() { ClrFullClassName = "System.Windows.Controls.ItemsControl" }, 3).Find<IControl>(new WPFPattern() { ClrFullClassName = "System.Windows.Controls.ContentPresenter", WPFControlOrdinalNo = 1 }).Find<IControl>(new WPFPattern() { WPFControlName = "Image" }, 4); // Image from TestLeft Image actuell_Picture = image.Picture(); // picture to compare with actuell_Picture BitmapImage expe33 = new BitmapImage(new Uri(@"C:\\expectedPicture.bmp")); Bitmap exp44 = new Bitmap(@"C:\\expectedPicture.bmp"); How to compare this actuell_Picture with a stored picture?I search in stackoverflow for comparing with BitmapImage, Bitmap,... No one works for me

TestLeft doesn't include an image comparison function, so you would need to import and use some sort of image comparison toolkit, for example this Simple Image Comparison toolkit for .NET . I should point out that SmartBear do not support 3rd party applications or toolkits, but you may get help from their respective communities.
