I am cropping parts of a psd in Affinity Photo so I can save these as jpegs or pngs to add to a website. When I just cropped a rectangular search bar background it should have shown 735px by 60px but now is showing unconstrained , 49 x 4 pixels which is totally off. Making the area smaller or larger makes the sizes jump up and down.. What am I missing here? The other issue is that I cannot enter the width or height boxes to change the amount of pixels. Any ideas what I am missing here?
