Adjusting Page Images Before OCR

You can rotate and straighten page images in OmniPage Pro’s image view before OCR takes 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 you click the Original Layout and Output Format button in the Manual OCR toolbar because all zones that were manually or automatically drawn are deleted during these operations, and the page will need to be re-processed.

NOTE: If you are processing your document automatically you can pause processing and adjust the page image after it is loaded or scanned by clicking Stop in the AutoOCR toolbar. Click Finish to continue automatic processing.

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.

  3. 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.

NOTE: 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.
