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.
