Adjusting Page Images Before OCR

Processing Documents
OmniPage Pro has many features that allow you to customize
processing and improve OCR results. Please refer to the online Help for
more information on these and other ways to improve OCR results.
You can rotate and straighten page images in OmniPage Pro's image
view before zoning and OCR take place. This is recommended to
improve OCR accuracy on pages that are not oriented correctly.
If you need to rotate or straighten a page, be sure to do so before
performing OCR because all zones are deleted during these operations.
To rotate a page image:
1 Click on the page image to make the image view active.
2 Click the Rotate Image button to rotate the image 90-degrees
(clockwise) at a time.
Or, choose Rotate ! in the View menu and select 90, 180, or 270
degrees.
To straighten a page image:
1 Click on the page image to make the image view active.
2 Click the Straighten Image button.
Or, choose Straighten Image in the View menu.
OmniPage Pro straightens the page image up to a maximum of
10 degrees. OmniPage Pro will not straighten a page if it
determines that it is unnecessary.
It is recommended that you have OmniPage Pro automatically
rotate or straighten pages if needed during OCR by simply selecting
the Automatically straighten page image and Automatically correct page
orientation options in the Process tab of the Options dialog box.
