How to get the pixel tolerance value?

Hello,    I compare 2 files. My goal is to set a warning message if the pixel tolerance is below a certain value. An error message if it is up to this value. How can I get the exact pixelTolerance...

    I'm not sure of way to get the difference value returned from not matching values, but you specify the tolerance in your compare.

    But for what you're doing I don't think you really even need it. You could just nest compares with varying tolerances.

     

      let maxDifference = 20;
  // check if they're identical
  if(!pic_1.Compare(pic_2)) {
    // if they're more than maxDifference log error
    if(!pic_1.Compare(pic_2, false, maxDifference, false, 5, 0)) {
      Log.Error()
    } else {
      // they're different but acceptable log a warning
      Log.Warning();
    }
  }
