Configuration

Configuration options for the Islandora OCR module can be found at http://path.to.your.site/admin/islandora/ocr, and include the following options:

• Tesseract: Islandora OCR requires the path to your Tesseract binary to function correctly. It also requires Tesseract to be version 3.02.02 or higher to function correctly.
• Languages available for OCR: Islandora can look for any additional OCR languages you have installed; these are chosen from a drop-down menu at time of ingest or derivative creation.

It is recommended to check the Tesseract page for more information on these options.
