Can we output difference of two .png image file into a new .png file after using Regions.Compare

Can we output difference of two .png image file into a new .png file after using Regions.Compare.

Hello, 

I am trying two compare two images say A.png and B.png using Region.Compare method.

Once compared, if any difference is observed then difference should be seen in new Diff.png file at some specified location of drive.

Is this possible ?
