Do you plan add to image editor perspective correction option?
I know it is image analysis, but it could be even manual possibility to select document corners and transform to square image.
Or maybe it is possible using some other control or functionality now?
Add a new image cropper control, which allows users to drag/zoom a selected image within a defined frame, so that the resulting image has a defined width and height. This should offer an experience similar to the Facebook app's screen for adding/updating your profile photo. The control should display the non-selected area of the photo with configurable opacity settings, and optionally allow for a resulting circular image.
