    Secret message:

     

    function Test()

    {

       var pic2 = Utils.Picture;

       pic2.LoadFromFile('D:\\img2.png');

      Regions.img1_png.Check(pic2, false, false, 1, 1);

    }

     

    Result:

    Click here to show or modify data of the checkpoint "img1_png".

    The images are not equal.

    The pixel difference is 1 %.
    The color difference is 20 %.

    There is a slight difference between the compared images. If you want the checkpoint to report them as equal, set its Pixel Tolerance parameter to 277.

    Update the "img1_png" checkpoint data.
