Capturing Images From Within Applications 3-11
The following table identifies the options available with each
Pixel Depth setting. Since both the Draft & fast and Best &
de-screening Quality options are available with all the Pixel
Depth settings, the table does not include these options. The
table also does not include the Text Enhancement Technology
and Auto Area Segmentation options; these are available only
when Pixel Depth is set to Black & White.
* When you choose 3 pass, your application does not use the Calibration,
Color Filter, or Saturation features in TWAIN; see Chapter 4 for more
information.
