Ah, ok.  That’s a bit confusing.  Perhaps for 2.0?
So what exactly does it mean if it’s off?  There is already a flag for 
ApplyRotation.
Exactly what pre-processing is done?

Subject: Re: Turning off ImageProcessing

We should change "enableImageProcessing" to "enableImagePreprocessing".  That 
flag covers the rotation.py and ImageMagick preprocessing, NOT ocr.

As for the warnings...I'm trying to figure out how to push those further 
towards the time of executing tesseract so that people who run tesseract get 
the warning, but those whose files never go down that path don't get the 
warning.

Is the EnableImageProcessing flag in TesseractOCRConfig honored?  It seems to

[main] WARN org.apache.tika.parser.ocr.TesseractOCRParser - 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.

Is the only way to turn off image processing to remove the OCR parser?  Can I 
enable/disable it programmatically?
The easiest way I found to disable it is to provide a bogus path (thanks to the 
hint in TesseractOCRParser#checkInitialization), but that still issues the 
above message (not sure why it can’t check first if the path is valid)

Is there a better way to do this?
