Zoom in where double-click takes place

[Sedins]

Feature request:

I'm about to finalize a project and tested the site, which integrates cropbox, on 10+ people with different backgrounds and technical skills.

What hit me was that many of them got confused while zooming the image. Majority thought that it would be easier to grasp if the image zooms in where the double-click (or pinch-to-zoom on touchscreens) takes place.

Is a change like this something to be considered (default or as an optional parameter)?

I am confused. Both double click to zoom and pinch zoom are already the default.

Check the demo. Please elaborate. Closing this issue for now.

I'll try to clarify:

1. Go here http://acornejo.github.io/jquery-cropbox/
2. Double-click or pinch on touchscreen f.ex. the smaller shed (garage) to the left in the picture
3. The plugin zooms in to the middle of the picture even if you double-clicked to the left

Most users was used to having the picture zooming in where they had double-clicked. I.e. the clicked location is centered in cropbox when zoom occurs.

Like zooming on Google Maps (and a lot of other maps). When double-clicking somewhere, they move the map to zoom in at the clicked location instead of "just" zooming in.

Hope it clears up a bit. Is a bit hard to explain this in text. Could do a nifty screenshot again otherwise :P

Got it. You want the zoom to be centered on the pinch or double click event.

That requires adding a new function that zooms centered on another point. Shouldn't be too hard, when I get some time I'll look into it. (If you want to take a stab at implementing it let me know and I will gladly include your modification in the library)

[Sedins]

Exactly. Would be great if it is possible to include that into cropbox.

Would be fun to familiarized with the library, but I have extremely little time left at the moment after work, kids and helping a company getting up and running I'm afraid. Hope it'll work out anyway though.
