PaperPort Getting Started Guide 25
Edit multiple images
The ability to process items as a group is often referred to as
batch processing. PaperPort provides batch processing
features so that you can quickly enhance, modify, or rotate
multiple image items in a single operation.
Select one or more image items on the desktop, and then,
on the Item menu, point to SET Tools, and select the desired command. See the
online Help for more information.
Changing the black and white points
You can do this to improve image quality by removing the very dark and
overexposed areas. All colors lighter than your chosen new white point will
become white. All colors darker than your chosen new black point are set to
black. A typical use for this is to remove a shaded gray background in a
document you want to OCR. Select one of the darker gray pixels from the
background and apply it as the white point. Then the background will become
white. Changing black and white points for a color photo will typically increase
its contrast, but may also change color values.
You can apply new black and white points to individual images, as described.
You can also apply them as an auto-enhancement to all new pages scanned
with a given scan profile.
