Hi.
I need to capture the zoom factor (positive or negative) of an image during zooming...in practice I would like to use this information to reposition a symbol (which does not belong to the image) in the same coordinates using the zooming factor to position recalculation.
I tried using touchimageview together with gesturedetector but on this view I can only intercept clicks.
I tried also different libraries and examples but none of them generate an event from which to take the zooming factor or something similar useful to the goal.
How can I do?
