I was reading the docs ( https://tesseract-ocr.github.io/4.0.0/a02186.html#a96899e8e5358d96752ab1cfc3bc09f3e ) and came across this apparent conflict and also noticed that the two paragraphs have overlapping content (i.e. datapath, language)
*The datapath must be the name of the parent directory of tessdata and must end in / . *Any name after the last / will be stripped.* The language is (usually) an ISO 639-3 string or nullptr will default to eng. *It is entirely safe (and eventually will be efficient too) to call Init multiple times on the same instance to change language, or just to reset the classifier. The language may be a string of the form [~]<lang>[+[~]<lang>]* indicating that multiple languages are to be loaded. Eg hin+eng will load Hindi and English. Languages may specify internally that they want to be loaded with one or more other languages, so the ~ sign is available to override that. Eg if hin were set to load eng by default, then hin+~eng would force loading only hin. The number of loaded languages is limited only by memory, with the caveat that loading additional languages will impact both speed and accuracy, as there is more work to do to decide on the applicable language, and there is more chance of hallucinating incorrect words. WARNING: On changing languages, all Tesseract <https://tesseract-ocr.github.io/4.0.0/a02358.html> parameters are reset back to their default values. (Which may vary between languages.) If you have a rare need to set a Variable that controls initialization for a second call to Init you should explicitly call End() <https://tesseract-ocr.github.io/4.0.0/a01625.html#ga38027513ee9c0348de1790bddcdc3391> and then use SetVariable before Init. This is only a very rare use case, since there are very few uses that require any parameters to be set before Init. If set_only_non_debug_params is true, only params that do not contain "debug" in the name will be set. *The datapath must be the name of the data directory (no ending /) *or some other file in which the data directory resides (for instance argv[0].) *The language is** (usually) an ISO 639-3 string or nullptr will default to eng. *If numeric_mode is true, then only digits and Roman numerals will be returned. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
