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.
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.
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.
You may want to change this option if your application misinterprets the
image data and stores your image in reverse of what you expect.
Hole Fill
— allows you to fill in the holes that are around the edges of your
document. The types of holes that are filled include: round, rectangular,
and irregularly shaped (e.g., double-punched or those having a slight tear
that could have occurred when the document was removed from a binder).
Do not turn Hole Fill on if you are scanning photos.
Document Type
Text with Graphics
: when the documents you want to scan contain a mix
of text, business graphics (bar graphs, pie charts, etc.) and line art.
Text
: when the documents you want to scan contain mostly text.
