I am working with a fairly complex GUI which has a logo in the upper left hand corner. Currently when the figure is resized, the image resize in direct proportion to the figure. As a result you can make really mess up aspect ratio. I tried disable stretch-to-fill, but it didn't seem to work., So his code doesn't necessarily end up with an aspect ratio of 4/3 unless the initial aspect ratio was 1. For example if the original image was 60 high by 600 wide (aspect ratio of 10), the new width would be 600*4/3 = 800. Since the height didn't change it's still 60 so the aspect ratio of the new image would be 13.33333, not 1.33333 as requested.
