grdcontour -T: add option to tick mark all closed contours
|Target version:||Candidate for next minor release|
Although this may not be a feature that would be critical in any kind of way, it still would be very nice to have;
What about adding an option, e.g. -T[+a], that would tick mark all closed contours (as opposed to just ticking the innermost).
I changed line 609 in grdcontour.c from
if (inside == 2) save[pol].do_it = false; /* Not innermost so mark it for exclusion */
if (inside == 2) save[pol].do_it = true; /* Not innermost so mark it for exclusion */
to make the sombrero example.
