Is it possible to zoom in (x2) on a specific layer at runtime?
Do I have to use the layer "set zoom offset" action? I tried using that, but no matter what value I put in it it makes the layer 50% of the normal size.
Zooming at runtime for individual layers works fine for me. And "set zoom offset" would be the correct action as well. It's the same as the ZoomX/ZoomY properties of the layer. Are you sure that you didnt change the ZoomX/Y RATE properties of that layer unintentionally. Since that could kind of explain things.
Other than that: share a cap.
