WARNING: Tesseract OCR is installed and will be automatically applied to image files unless
you've excluded the TesseractOCRParser from the default parser.
Tesseract may dramatically slow down content extraction (TIKA-2359).
As of Tika 1.15 (and prior versions), Tesseract is automatically called.
In future versions of Tika, users may need to turn the TesseractOCRParser on via TikaConfig.
