I'm trying to edit this skin's start button: https://www.wincustomize.com/skins.asp?searchtext=longhorn+slate+4051&sort=updatedate&order=Descending&library=1 but when I don't know how to make the canvas size smaller ( when I say canvas I mean the area of which the image is shown, not shrinking the entire image itself ). At first I suspected that you edit the margins of the image, but when I changed that, nothing seemed to change. Please help, I'm sorry I'm such a noob. Thanks.
