@romainboucher thanks a lot for your work. i also started with wescan but couldn't find time to make progress. so thanks a lot for contributing. i will merge it in master. but i think the unittests are failing for now. maybe you can fix them.

Hi @jachzen Do you have time to finish this, i think Roman is quite busy with his own work. Thanks @jachzen !

[saileshbro]

hi @romainboucher, is there any way we can pass the file path of the image in memory and open the cropper only without letting user click image/select from gallery?
