When resizing images, it would be great to have a smart constrain proportions check options, so the user can simply choose either by H or W and know that the image original appearance is retained. This is ideal when working with logos.
Rvela, it works the same way it does in HTML. If you type in a width in the W field it will keep the appearance proportional. Same thing if you add a Height and leave the Width blank. If you type in a value for both then it might sqeeze the image out of its original proportions.
You sir, are correct. Case closed!
