Novice in the use of hype, I wanted to know if it is possible to associate the actions with the sliding of the fingers on the pad of my macbook pro without clicking on the pad. For example two fingers up to enlarge an image.
Definitely possible: Since a two finger movement is captured as a 'scroll' event, you want to look at the scroll position and match that with an animation's point in time. (enlarging an image over a timeline for example). These threads might help you out:
Thanks a lot for your help and for the informations Daniel
