A mode used to scale the canvas area if the aspect ratio of the current resolution doesn't fit the reference resolution.
MatchWidthOrHeight | Scale the canvas area with the width as reference, the height as reference, or something in between. |
Expand | Expand the canvas area either horizontally or vertically, so the size of the canvas will never be smaller than the reference. |
Shrink | Crop the canvas area either horizontally or vertically, so the size of the canvas will never be larger than the reference. |
