Справочник Пользователя для Nuance OmniPage 15

The Image Enhancement tools can also be used to edit images to save and 
use them as image files. Note that some tools of OmniPage 15 work only 
on this, so-called Primary image, others on the one used for OCR (OCR 
image). Click the Primary/OCR Image button in the Image 
Enhancement window, to see the current state of either image.

The Image Enhancement window has two panels. The left panel shows 
the starting image. Your changes are shown in the right preview panel. 
When you click Accept, the right image is moved to the left panel to 
become the new starting image for further enhancement.

The following tools are accessible on the toolbar:

Pointer (F5) - the Pointer is a neutral tool carrying out different 
operations under different circumstances (for example, to pick a 
color for the Fill operation, or to catch the deskew line.) 

Zoom (F6) - click the tool then use the left mouse button to 
zoom in on your image or the right mouse button to zoom out. 
You can also use the mouse wheel for zooming in and out - even 
in the inactive view. In the active view the "+" and "-" buttons 
serve the same purpose.

Select Area (F7) - click and draw your selection on the image to 
use a tool only on the selected area. (Image Enhancement Tools, 
by default, work on the whole page.) Selection has three modes 
(in the View menu):

Normal - you can select rectangular areas on the page, then move 
or resize the selection.

Additive - this mode enables you to make irregular selections by 
drawing overlapping rectangles that will be added to each other.

Subtractive - use this mode to cut out parts from your existing 
selections by drawing overlapping new areas.
