Sorry in advance to bother you all with this question, but I have exhausted by resources.
Let's say I wanted to pinch an image in a view and scale it dynamically as the fingers are moving. Eg like the google maps app or the photo app.
Before I proceed, is there any sample code on such a thing out there?
Anyway, this is what I have so far that doesn't work:
I have a method converts the distance between two fingers into a euclidean distance.
As the fingers move, I take a ratio of the new distance between fingers and old distance between fingers. I then transform the picture with this ratio using one of the MakeScale functions.
Somehow this looks really bad when executed.
I realized that the maps/photo app must do something differently. Maybe it tracks each finger separately?
Any help would be appreciated.
thanks much
