When Tesseract/Cube is initialized we can choose to instantiate/load/run only the Tesseract part, only the Cube part or both along with the combiner. The preference of which engine to use is stored in tessedit_ocr_engine_mode.
ATTENTION: When modifying this enum, please make sure to make the appropriate changes to all the enums mirroring it (e.g. OCREngine in cityblock/workflow/detection/detection_storage.proto). Such enums will mention the connection to OcrEngineMode in the comments.

+------------------+ Orientation Example: | 1 Aaaa Aaaa Aaaa | ==================== | Aaa aa aaa aa | To left is a diagram of some (1) English and | aaaaaa A aa aaa. | (2) Chinese text and a (3) photo credit. | 2 | | ####### c c C | Upright Latin characters are represented as A and a. | ####### c c c | '<' represents a latin character rotated | < ####### c c c | anti-clockwise 90 degrees. | < ####### c c | | < ####### . c | Upright Chinese characters are represented C and c. | 3 ####### c | +------------------+ NOTA BENE: enum values here should match goodoc.proto
If you orient your head so that "up" aligns with Orientation, then the characters will appear "right side up" and readable.
In the example above, both the English and Chinese paragraphs are oriented so their "up" is the top of the page (page up). The photo credit is read with one's head turned leftward ("up" is to page left).
The values of this enum match the convention of Tesseract's osdetect.h

enum of the elements of the page hierarchy, used in ResultIterator to provide functions that operate on each level without having to have 5x as many functions.

Possible modes for page layout analysis. These *must* be kept in order of decreasing amount of layout analysis to be done, except for OSD_ONLY, so that the inequality test macros below work.

JUSTIFICATION_UNKNONW The alignment is not clearly one of the other options. This could happen for example if there are only one or two lines of text or the text looks like source code or poetry.
NOTA BENE: Fully justified paragraphs (text aligned to both left and right margins) are marked by Tesseract with JUSTIFICATION_LEFT if their text is written with a left-to-right script and with JUSTIFICATION_RIGHT if their text is written in a right-to-left script.
Interpretation for text read in vertical lines: "Left" is wherever the starting reading position is.
JUSTIFICATION_LEFT Each line, except possibly the first, is flush to the same left tab stop.
JUSTIFICATION_CENTER The text lines of the paragraph are centered about a line going down through their middle of the text lines.
JUSTIFICATION_RIGHT Each line, except possibly the first, is flush to the same right tab stop.
Definition at line 217 of file publictypes.h.
The text lines are read in the given sequence.
In English, the order is top-to-bottom. In Chinese, vertical text lines are read right-to-left. Mongolian is written in vertical columns top to bottom like Chinese, but the lines order left-to right.
Note that only some combinations make sense. For example, WRITING_DIRECTION_LEFT_TO_RIGHT implies TEXTLINE_ORDER_TOP_TO_BOTTOM
Definition at line 136 of file publictypes.h.
The grapheme clusters within a line of text are laid out logically in this direction, judged when looking at the text line rotated so that its Orientation is "page up".
For English text, the writing direction is left-to-right. For the Chinese text in the above example, the writing direction is top-to-bottom.
| WRITING_DIRECTION_LEFT_TO_RIGHT | |
| WRITING_DIRECTION_RIGHT_TO_LEFT | |
| WRITING_DIRECTION_TOP_TO_BOTTOM |
