The following figure shows the TWAIN interface for scanning from
PaperPort and other applications that use the TWAIN standard. Note
that some of the options on the window may not be available, and will
be greyed out if they are not appropriate for your scanner.
The options for the Visioneer Strobe XP 220 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.
Greyscale 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.
