Hide Overflow allows you to render your output content as seen the design, or fill the user screen. This is good when outputs with a
full or fixed width are required.

If enabled, this will mask the output so any layers with positions beyond the size of the body of the PSD document will not be visible.
If disabled, your output will stop at your design width and prevent conent from displaying outside the document size.

Hide Overflow and
Align Output to create unique outputs from the same design.
