Summary

When you OCR a document using the OmniPage OCR engine and you do not enable the Rotate Image automatically image clean-up option, you may receive unintelligible text even though the image appears fine.

Cause

The OmniPage OCR process may be OCRing the image in an incorrect orientation. This issue can arise if the images in a document were manually rotated in the Laserfiche Document Viewer. While the images are now oriented correctly in the document viewer, the image files stored on disk are still rotated. The OCR process is not correctly taking into account the image orientation in the Laserfiche Document Viewer.

Resolution

There is a hotfix available for Laserfiche client 7.2.1. The fix includes updated versions of the following files:

• BPOmniOCR.exe (version 7.2.1.3)
• OmniOCRWrapper.dll (version 7.2.1.3)
• OmniPage32.lfo (version 1.0.0.3)

To update the OmniPage OCR components

1. Close any applications that may be using the OmniPage OCR engine.
2. Click the following link to download a zip file containing the hotfix files.
