Image Processing tab
The Image Processing tab provides the following options.
General Options
•
Deskew
⎯
automatically straightens a document within ±0.3
degrees of the leading edge of the document. Deskew can detect up
to a 45-degree skew and correct up to a 24-degree angle at 200 dpi
or a 10-degree skew angle at 300 dpi. This option is only available
when
Automatic
is selected.
NOTE: To prevent data loss, the document must have all four
corners within the image path.
•
Halftone Removal
⎯
enhances images containing dot matrix text
and/or images with shaded or colored backgrounds using halftone
screens and effectively eliminates noise caused by the halftone
screen.
•
Invert Image
⎯
allows you to select how the black pixels will be
stored in the image. By default the black pixels are stored as black
and the white pixels are stored as white. Turn this option on if you
want the black pixels stored as white and the white pixels stored as
black.
NOTE: You may want to change this option if your application
misinterprets the image data and stores your image in
reverse of what you expect.
•
Add Border
— allows you to add a fixed amount of border to the left,
right, top and bottom edge of the image. This option is not available
when
Aggressive
is selected.
