Using OCR on Tiff Images

  Asked By: Janet    Date: Sep 03    Category: Sharepoint    Views: 2923

Is anyone successfully using SharePoint to search .tiff images for content
using the OCR capabilities?

If so, can you please relay the steps you went through to get it to work?
Are there any special settings or service packs (fixes) required or
limitations anyone has run into? We cannot get it to work here.

We have many tiff images and we would like to be able to search for specific
images based on a word or string of text or numbers that is stored as part
of the image.

did you use the reg-file stored  on the SPS - CD ? If not - it's
activating OCR for SPS. If you can not find the reg-file look at
www.sharePointInfo.de <http://www.sharepointinfo.de/> there you will
find it.

Enable Optical Character Recognition in tiff  Files
If you enable OCR, sharepoint  Portal Server scans the TIFF document and
attempts to recognize characters so that additional information can be
included in the index. However, scanning is resource-intensive.

If you enable OCR, SharePoint Portal Server does not include any single-page
TIFF file larger than 1 megabyte (MB) in the index due to memory impact.
SharePoint Portal Server includes multi-page TIFF files in the index
regardless of the MaxImageSize registry setting. You can edit the registry
to change the file size limit. In addition, if you enable OCR, you can
enable automatic file rotation to increase the scanning accuracy of files
that are oriented upside down or sideways. For more information, see Change
the TIFF File Size Limit and Enable Automatic File Rotation.

OCR recognizes English, European, Cyrillic, Greek, and all related character
sets (code pages 1250, 1251, 1252, 1253, and 1254). It does not recognize
complex scripts such as Arabic, Thai, Hebrew, Japanese, Chinese, and Korean.

CAUTION Be careful when editing the registry. If there is an error in your
registry, your computer may not function properly.

To enable optical character recognition in TIFF files

- On the taskbar, click Start, and then click Run.
- Type regedit, and then click OK.
- In Registry Editor, navigate to
- Right-click MSPaper, point to New, and then click DWORD Value. A new key
- Name the key PerformOCR.
- Right-click PerformOCR, and then click Modify. The Edit DWORD Value dialog
box appears.
- In Value data, type 1. To disable optical character recognition, type 0.
- Click OK.
- Close Registry Editor.
- Restart MSSearch. To do this:
- On the taskbar, click Start, point to Programs, point to Administrative
Tools, and then click Services.
- Right-click Microsoft Search, and then click Restart.
- You can also enable ocr  by double-clicking tiff_ocr_on.reg in the
Support\Tools directory on the SharePoint Portal Server CD.
