Nyall Dawson	12e34f2672	[expressions] Allow make_point to accept z/m values, add new ... make_point_m for creation of PointM geometries. Also add m(point) and z(point) functions for retrieving z/m value of a point or node.	2015-11-06 20:09:13 +11:00
Juergen E. Fischer	82b34afe03	move remaining function_help to json and update it's translation handling	2015-09-20 18:35:27 +02:00
Nyall Dawson	55027e545f	Clean up and extend expression geometry functions: ... - New expression functions for area(geom), perimeter(geom), point_n(geom), start_point(geom), end_point(geom), make_point(x,y) - Add new variant to length() function which takes a geometry object, allows for length(geom) evaluation. - Rename x_at, y_at to $x_at, $y_at (alias old names) to reflect that these only work on current feature geometry - Add x(geom), y(geom) functions which return x and y coordinate for point geometries or centroid x/y for non-point geometries (fix #11008)	2015-09-18 09:09:09 +10:00
