get_chapter_info — Get information concerning the chapters on operators.
该算子 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 该算子
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 UTF-8.
