get_keywords — Get keywords which are assigned to operators.
The operator get_keywords returns all the keywords in the online-texts corresponding to those operators which have the indicated substring OperatorName in their name. If instead of OperatorName the empty string is transmitted, the operator get_keywords returns all keywords. The keywords of an individual operator can also be called by using the operator get_operator_info. The online-texts will be taken from the files operators_[LANG].ref, operators_[LANG].sta, operators_[LANG].num, operators_[LANG].key and operators_[LANG].idx, which are searched by HALCON in the currently used directory and in the directory 'help_dir' (see also get_system and set_system).
The encoding of the result is ISO 8859-1 for English and German, and UTF-8 for Japanese.
