White point: Sets the white point of the image. All data that is lighter 
than the white point value will appear as white in the image.
Black point: Sets the black point of the image. All data that is darker 
than the black point will appear as black in the image. 
These additional options (also scanner-dependent) are available in the Scan 
Controls window:
Scanner speed: You can set some scanners to operate at full speed or at a 
percentage of full speed. It is recommended to scan complex documents at a 
low speed to avoid overloading the system. This option is not available on 
some scanners.
Scan file format: You can save scanned images as CALS Group 4, TIFF 
Group 3, TIFF Group 4, CT1and PDF raster files. 
Resolution: Allows you to select a scanning resolution of 200 or 400 dpi. A 
higher resolution value produces higher quality prints and larger file sizes. A 
lower resolution reduces scanning time and file size but produces lower 
quality images. 
If 200 dpi is selected, some scanners will clip up to 1/4" off the leading edge of the 
image being scanned. If the actual image does not go all the way to the edge of the 
medium, this is not a problem.
Image buttons:
Mirror image button: Click this button if you want the image to be 
scanned as a mirror of itself.
Invert image button: Click here to invert the colors in your scanned 
images. This causes the white portions of the document to become black 
in the scanned image, and vice versa. This option is not available on the 
Xerox 7396 scanner.
Auto view button: When you select this option, images display in the 
Image Viewer as they are scanned.
Auto length button (Océ 9800 scanner): The Océ scanner normally scans 
images to standard sizes. However, if you want the image to be scanned to its 
actual length, click this button.
Auto scan button: When you click this, the Scanner Interface is put in 
automatic scan mode. Auto Scan is useful when you have several images with 
the same general characteristics (they are all dark sepia, for example). Once
