Thanks for the issue @ManishaQw!

As far as I can recall, the library doesn't support disabling zooming of the scroll view. It's probably pretty easy if anyone wants to add it though!

We are too facing an issue when i start cropping the image ,the image gets zoom in along with the cropbox.

We really want that image should not zoom in only the dropbox would rotate.It would be grateful if you provide some help regarding that.

Hey folks! @cupnoodle made a PR to disable the ability to use pinching to zoom images, but I'm getting the feeling that's not what the two of you are requesting here. I had a play with that, but it feels so broken that I don't think it's a good idea to add.

Are you instead requesting that after you change the shape of the crop box, the reset animation where all of the content zooms in to fill the screen around the crop box is disabled instead?

@TimOliver I have enabled the circular mode and changed the shape of crop box to 3:4. I have also added provision to update crop view with new image from a crop picker collection view below. However I am not able to solve this issue when image keeps zooming in when new image is assigned to crop view. I am tweaking the "setup" method in "ToCropView". Any help what I am missing here.

@ashishpatill Hi Ashish! Uh, it might be better to open a new issue instead of posting that in here. :)
