Request: Safari like pinch and zoom

General
1

Hey guys

This is a big ask, but it might be a challenge for someone wanting to flex their Codea muscles.

I want to make a pinch and zoom class that somewhat resembles Safari on the iPad

So, in a nutshell, I want the class to work like this:

  • the drawing zooms based on where you pinch. If you pinch in the top left corner, it zooms in on that area.

  • you can move the drawing around, but there’s a limit to how far you can drag it

  • when you zoom far enough back out, the drawing springs back to its original shape

Herwig’s Zoom Library is a great starting point, but I just can’t tweak it to get the results I want.

Any ideas would be greatly appreciated.

Thanks
