getBounds help

[crunchie 0 Likes (Newbie)]

I am using a slider component to scale my transform item, however my (poor) calculation as to what max width and height could be for the item is flawed and the max width or height ends up bigger than it should be when i set the slider to max.

 

I believe that i need to compare the transform bounds to the items bounds and work it out from there. Unfortunately, i am not well versed in geometry and was hoping that someone could shed some light on how to do this based on the current rotation / scale of the transform item.

 

Thanks very much,
