19.31. Handwritten pages are rotated by Symphony OCR when they shouldn't be

Background

Handwritten documents are upside down after having been processed by Symphony OCR.

Symphony OCR has the setting to Automatically Rotate documents turned on by default.  It makes every effort to determine the proper orientation for handwritten documents, however, handwriting makes the page orientation often hard to determine. 


Resolution

Unfortunately, this algorithm is not something that can be tuned, so you have two options:

  • Turn off automatic page rotation
    • Open Symphony OCR
    • Choose "Processor"
    • Under "Basic Settings", uncheck the "Automatically rotate pages to proper orientation" check box
      Note: this will disable the rotation for all documents
  • Turn on logging to indicate which pages have been rotated:
    • On the workstation running Symphony OCR, navigate to C:\Program Files (x86)\Trumpet\SymphonyOCR\config
    • Open the log4j.properties file using notepad
    • Change the "log4j.logger.autorotatelog=ERROR, AUTOROTATEFILE" line to "log4j.logger.autorotatelog=INFO, AUTOROTATEFILE".
    • You will now have a listing of files that have been rotated in a log file at: 'C:\Program Files (x86)\Trumpet\SymphonyOCR \ogs\autorotate.log' file., and can manually re-rotate them.
