Image cropper, in browser works ok in ionic works very slow and laggy


#1

Hi,

I am trying to implement an image cropper inside an ionic app, I have tried multiple cropper libraries like cropper.js for example. 
Testing it in the chrome browser of safari browser on the mobile phone it works as expected, the moment I add the same exact code and import the library in the  ionic app and try to perform the exact same tasks it barely works, very slow to perform the same task of selecting a region of an image.

Is there something I am doing wrong, is there a better way to do this, the end result I want to have is: 

Have an image
select part of it
use that part of it
go back to the image select another part
use the other part an so on

Many thanks.
