[rafeekabid]

Hi Team,
Subject: pytest-needle 0.3.11
In report, unable to get screenshot with colour difference like Heat map difference. Its showing actual screen shot, expected screenshot and difference screenshot. but unable to find what is the difference between two screenshot with color change. Is there any workaround for this.
I tried in different engine like PIL,Perceptualdiff etc..
Thank in advance.

Regards,
