SCANNING WITH THE TWAIN INTERFACE 103
THE TWAIN INTERFACE OPTIONS
This TWAIN interface is an example of the window you will see for
your scanner. Some of the options on the window may not be available,
and will be greyed out if they are not available with your scanner.
The options on the Visioneer Patriot 470 (Strobe XP 470) TWAIN
interface are:
Mode—Select a scanning mode:
Black&White to scan in black and white. The scanning pixels
are all the same size and are either black or white. Use this
setting for letters, memos, and other black and white material.
This scan mode produces the smallest file size.
GrayScale to scan items such as documents containing
drawings or black and white photographs. The scanning
produces an image of up to 256 shades of gray. You can also
scan a color document to turn its colors into gray shades. The
file size is about one third that of a color scan.
Color to scan magazine articles, photographs, and other color
images in full color. Color scans have the largest file size.
