Re: [tesseract-ocr] Re: setting user-words in api?
I haven't tried user_words yet.

Re: [tesseract-ocr] Re: setting user-words in api?
I have made a wiki page for using user_patterns with API. Please see
https://github.com/tesseract-ocr/tesseract/wiki/APIExample-user_patterns
You can try similarly for user_words.

Re: [tesseract-ocr] Re: setting user-words in api?
Thanks, I already tried api->SetVariable("user_words_suffix", "user-words");
Did not work, while specifying it in a config file and using the command
line tesseract tool it works.
I used a file monitor tool to see if the process tries to open a user-words
file, but it did not. The tesseract tool however does.
I am aware of https://github.com/tesseract-ocr/tesseract/issues/960
But I am using 4.1, where this is fixed.
Do you have a working example?
