Member	Description
DetectPageOrientation	OCR engine should detect page orientation only. Tesseract OCR engine needs "osd.traineddata" dictionary if this mode is used.
RecognizePageWithPageSegmentation	OCR engine should segment image and recognize text from image that contains different content (text, images, etc).
RecognizePageWithPageSegmentationAndOrientationDetection	OCR engine should segment image, detect text orientation and recognize text from image that contains different content (text, images, etc). Tesseract OCR engine needs "osd.traineddata" dictionary if this mode is used.
RecognizeSingleColumn	OCR engine should recognize text from image that contains a single column of text of variable sizes.
RecognizeSingleBlockOfVertText	OCR engine should recognize text from image that contains a single uniform block of vertically aligned text.
RecognizeSingleBlock	OCR engine should recognize text from image that contains a single uniform block of text.
RecognizeSingleLine	OCR engine should recognize text from image that contains a single line.
RecognizeSingleWord	OCR engine should recognize text from image that contains a single word.
RecognizeCircleWord	OCR engine should recognize text from image that contains a single word in a circle.
RecognizeSingleChar	OCR engine should recognize text from image that contains a single char.
RecognizeSparseText	OCR engine should recognize text from image that contains sparse text. OCR engine tries to find as much text as possible in no particular order.
RecognizeSparseTextWithPageOrientationDetection	OCR engine should detect text orientation and recognize text from image that contains sparse text. OCR engine tries to find as much text as possible in no particular order. Tesseract OCR engine needs "osd.traineddata" dictionary if this mode is used.
RecognizeRawLine	OCR engine should treat the image as a single text line.
