Invert may be most useful for processing documents received from
a fax modem or TWAIN source. These types of documents
sometimes have white text on a black background. Such
documents must be inverted before TextBridge can perform OCR.
Deskew
The Deskew command is active only when TextBridge Pro is in
preview mode. This command straightens the current page image
if it is incorrectly aligned. Deskew is only available once per page.
The Deskew command will be dimmed if the Output Layout
Note
setting is Recompose Text or Recompose All because these
settings cause TextBridge Pro to deskew the page automatically
as part of preprocessing. This feature does not effect the
quality of the output.
Enhance Display
The Enhance Display command is active when you are in either
preview or interactive training mode. By default, this command is
off; when you turn it on, however, it stays on until you turn it off
again.
Enhance Display improves the view of both pictures and text.
Scanned images normally display in only black and white; when
Enhance Display is on, images are displayed in black, white, and
several shades of gray. The result is a significantly improved
onscreen display of pictures and sharper text.
This feature does not affect the quality of the output.
Using the Enhance Display feature on computers with older
Note
operating systems could take longer to display images in the
preview screen.
