point pattern fill
A new option exposes the ability to clip markers in the fill by:
- "Clip to shape": default behaviour, same as previous versions. Markers
are clipped so that only the portions inside the polygon are visible
- "Marker centroid within shape": only markers where the center of
the marker falls inside the polygon are drawn, but these markers
won't be clipped to the outside of the polygon
- "Marker Completely Within Shape": only markers which fall
completely within the polygon are shown
- "No clipping": any marker which intersects at all with the polygon
will be completely rendered
The clipping mode can be overridden via a data driven expression if
desired.
