How to get the diff image from VisualTest in TestComplete

As rraghvani​ suggested VisualTest specific questions are best posted on the specific forum.

You can programmatically compare images https://support.smartbear.com/testcomplete/docs/reference/program-objects/picture/difference.html and save the difference image  to file https://support.smartbear.com/testcomplete/docs/reference/program-objects/picture/savetofile.html

I made a pretty crude diff image just using defaults with the bare settings.  There are other settings you can enable and sending email in code isn't too hard you just need a local email server to run it through.

Thanks you !

This is some JavaScript code for TestComplete that will compare two saved images and produce a Diff image...

function Test1()
{
  Pict1 = Utils.Picture;
  Pict2 = Utils.Picture;

  Pict1.LoadFromFile("C:\\Temp\\baseline.jpg");
  Pict2.LoadFromFile("C:\\Temp\\actual.jpg");

  /* Comparing the images using the Compare method
  if (!Pict1.Compare(Pict2))
  {
    Log.Picture(Pict1);
    Log.Picture(Pict2);
    Log.Error("The compared images are not identical");
  }*/

// Comparing the images using the Difference method
  ResultImage = Pict1.Difference(Pict2);
  if (strictEqual(ResultImage, null))
    Log.Message("The images are identical");
  else
    Log.Picture(ResultImage);
    ResultImage.SaveToFile("C:\\Temp\\diff.jpg");
}
