I agree more examples would help.

As I haven't used the functions myself (I'm just the janitor)
unfortunately I don't have any better answer than what I believe
you've found by yourself browsing sources and the documentation:
(Though arguable the code in the test-suite doesn't serve being
an example here.)

Starting with an image of unknown topology (or processed to
likely contain shapes want to further investigate), with N being
4 or 8 for the connectivity, iterate, use rapp_contour_Nconn_bin
to get each shape, then rapp_fill_Nconn_bin to fill it, to
prepare for the next call to rapp_contour_Nconn_bin.  Repeat
until an empty contour string is returned.
