Zoom Advanced Script

[antoniocpaulo]

Hi!
Let me start by thanking you for your code on the zoom advanced script.
I am trying to incorporate some of it in my GUI, however I am struggling to get it to fit my initial frame.
My example image is 2400x3600 (wxh) (first screenshot) and my initial frame is (300x600) and I would like to show the image resized so that it would fit inside the frame (second screenshot).
I have tried to change the initial scaling, the size of the container, however I cannot make it work.
Do you know how can I do it?
Many thanks!
