Surrounding void amount adjustment

The void amount around the network scanned image is adjusted.
In network scanning, since the void amount is very small in stored images, a shadow may appear
around the scanned image due to the subtle difference in the original sizes. This shadow can be
eliminated by adjusting the setting value.
The setting value is applied to all resolutions and color modes.
