that you wish to scan.
To specify your settings, enter the dimensions manually in the width and height
edit boxes; or use the Scan Frame tool to define or resize your scan frame.
Changes made in the Preview window are automatically displayed in the Scan
Frame setting edit boxes.
If you wish, you can also choose from a menu of predefined Scan Frame
settings. To do this, point your mouse to the words "Scan Frame" in the Settings
window, and choose the setting you wish from the drop-down menu that
appears.
