get_chapter_info — Get information concerning the chapters on operators.
The operator get_chapter_info gives information concerning the chapters on operators. If instead of Chapter the empty string is transmitted, the routine will provide in Info the names of all chapters. If on the other hand a certain chapter or a chapter and its subchapter(s) are indicated (by a tuple of names), the corresponding subchapters or - in case there are no further subchapters - the names of the corresponding operators will be given. The organization of the chapters on operators is the same as the organization of chapters and subchapters in the HALCON-manual. Please note: The chapters on operators respectively the subchapters concerning an individual operator can be called by using the operator get_operator_info(::<Name>,'chapter',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 will be searched by HALCON in the currently used directory or 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.
