2-16 Understanding EPSON TWAIN Pro Features
Changing Resolution
The resolution for the current scanning operation can be changed
by selecting a resolution or typing in the value. This setting
overrides the resolution setting you make in the Destination
dialog box.
Source and Target image sizes
The Source fields indicate the size of the image that is displayed
or selected in the Preview window.
The Target fields indicate what size the image will be when it is
output.
Note:
The image size setting is closely related to the Resolution. If you change
either setting arbitrarily, the resulting image may not be what you
expect.
