Edge Fill
Corrects shadowing around the borders (the edges of the scanned
document) by filling them with the selected color.
Note:
Certain settings may not be available, or may be automatically selected, depending on the type of
image you are previewing and other settings you have selected.
You can customize how certain Epson Scan settings behave by clicking
Configuration
and
changing settings in the window that appears. See Epson Scan Help for details.
