Hello everyone. I have a GUI where I am loading an image into the axes. I want the axes to wrap around the loaded image's native resolution, much like a MATLAB figure window would do.

How can I do that? Thanks in advance.

Thanks for the truesize command. Didn't know about that.

But I wanted to mean the axes ONLY to wrap around the figure, not the whole figure window. truesize is setting my whole GUI figure window to the figure size.
