The following unit tests are failing in Tesseract 4.1 build (branch features\321-Tesseract-4):

  • EngineTests.CanProcessDifferentRegionsInSameImage
  • EngineTests.CanProcessSpecifiedRegionInImage

seems to be related to tesseract-ocr/tesseract#845

More specifically setting setting the region of interest (SetRectangle in tesseract) to anything other than the dimensions of the pix causes erroneous results (random sting output).

I just stumbled about this bug as well. Is there a chance it will be fixed soon?
