This is an Angular 2 component I wrote to experiment with key bindings and gestures for cropping an image using SVG image masking; so it doesn't actually perform the cropping. Keyboard input is only accepted when the focus is on the image.
There is a delay in starting the rotation due to the vertical motion being interpreted as a scroll event. It starts rotation sooner if there is a horizontal component in the panning motion.
The demo is at: https://saschwarz.github.io/angular2-image-crop/index.html
