Ember image crop before upload

Actually i’m using ember-plupload to send images to S3. I need to crop images before upload.

Does anynone have a direction/experience in that?

Thanks!

Using a canvas element works really well. I don’t have any code handy to show you (and none of it is in an Ember app anyway) but search online for “html5 crop image canvas” or suchlike to get started.
