9. Select the
Cropping
option from the drop-down list. When
Auto-Crop
and
Deskew
are enabled, there are three choices for the type of cropping to be
performed:
Automatic
— the image is auto-cropped by the scanner. A slight amount
of black border may still exist on the edges of the images.
Aggressive
— the image is auto-cropped by the scanner with the goal of
completely removing any remaining black borders that may be left over
after regular auto-crop and deskew processing.
NOTE: Image content at the image edges may be affected. If you are
scanning documents that have content at the edge of the paper,
you may need to select
Automatic
cropping.
Relative to document
— the image is auto-cropped and deskewed by the
scanner. The settings on the Mask tab of each Image Setup (see the
section entitled, “Using Image Setup” later in this chapter) to determine the
portion of the auto-cropped and deskewed image produced by the
scanner.
NOTES:
Relative to document
is only available for the i280 Scanner.
Also known as Zone processing
. Zone processing in the i200
Series Scanners allows you to define different zones for bitonal
and color images when dual-stream scanning. It is particularly
useful, for example, in insurance applications where a claim form
may contain a photograph of a damaged vehicle. With Zone
processing, you can produce a bitonal image of the entire claim
form while at the same time producing a color image that contains
only the photograph.
10. Select the
Bitonal overcrop
check box to remove pixels from all sides of
an auto-cropped image (i.e., when Capture Software performs additional
auto-cropping).
NOTES:
Overcrop
is not yet functional on color or grayscale images.
When enabled, only bitonal images will be affected.
Overcrop
is only available for selection when
Remove black
borders
(with or without Deskew)
is enabled.
11. Enter the amount of overcrop in 1/100 of an inch (0 to 75).
12. If you want to add pixels to the right or bottom edge of the image to make it
MOD 8 compliant, click the
Enlarge image width of bi-tonal images to a
multiple of 8 pixels
check box.
Mod 8 compliant means that the number of horizontal pixels of an image is
a multiple of eight; some applications require Mod 8 images.
NOTE: This option will only affect black-and-white images. Color images
are not supported.
13. Select the
Long paper
check box when scanning documents that are
longer than 32 inches. This option is only available with the i280 Scanner
and when Auto-Crop and Deskew are disabled.
When enabled, the scanner (when started) scans the scroll of paper
continuously until there is no more paper. As it is scanning, the continuous
image stream is divided into individual images based on the settings on the
Mask tab on the Image Setup dialog box. For instance, if a 100-inch long
document is scanned and the
Height
value on the Mask tab is set to a
value of 10 inches, then the scanner will produce 10 images each 10
inches long.
