NOTE currently scatter and place rules use different discreet selectors.
Most basic discrete selection is just a list of parameter values on the range [0, 1]:
[pos1, pos2, ... posn]
One can also specify the interval between the items:
[item_offset]
It is possible to specify start offset
[offset_start : item_offset]
Or end offset:
[item_offset : offset_start]
Or both:
[offset_start : item_offset : offset_end]
- offset_start, offset_end (double), the distance between the start of the edge and the first item, or respectively end of the edge and the last item. double values
- item_offset – either:
- ninterval_count (int) – number of intervals between items; e.g. to place n items interval count is n-1
- linterval_length (double) – desired interval length, could be less or more, depending on how many items fit in the area.
