When the Add Full Size Art Region button is clicked, it adds an art region with each edge being Margin Size units away of the corresponding edge of the image.
If Margin Size is zero, the art region added will be the full size of the image.
For Additional Information: See Add Full Size Art Region which is used with the Margin Size.
Changing the Margin Size value won’t do anything by itself.
It has to be used in conjunction with the Add Full Size Art Region button.
