User click on Mask & upload the image....
Its displaying same image two times, also Edit Text is displaying on image....
Once user click on Edit Text, we are displaying pop up box....
There we can see Zoomin & Zoomout buttons are displaying....
Issue :
Once we click on those buttons, its zooming the outside image, but not the inside image....
Requirement :
So I want to replace the Inside image by outside image & Delete the Inside image , so that zoom feature will work for uploaded image....
