How to detect the Left-Top Corner of a Rectangle around an Object?

If I have an object on a surface and I want to find
out the left-top corner of the minimal rectangle
around it (i.e. the box crops the transparent part)
can I do that?

thanks

If you know the vertex coordinates it’s simply the min x and min y of
them.
