margin is set
Instead, split this behaviour off into a new "Line border (Nautical)"
grid style. It's a very specific type of effect and won't always
be desirable when using margins with the line border style.
Iterates over the geometries in the collection, allowing this type
of code:
gc = QgsGeometryCollection()
gc.fromWkt('GeometryCollection( Point(1 2), Point(11 12), LineString(33 34, 44 45))')
for part in gc:
print(part.asWkt())
- Calling removeGeometry with an invalid index will now raise an IndexError
- Calling collection[0] will return the first geometry in the collection,
collection[1] the second, etc. And negative indices return from the end
of the collection, so collection[-1] returns the last geometry in the collection.
- Geometries can be deleted by calling `del collection[1]` (deletes the
second geometry from the collection). Also supports negative indices
to count from the end of the collection.
or as embedded files.
Just like the SVG and raster image marker, raster fill can now
be set to use HTTP(s) URLs or have files directly embedded
inside the symbol itself.
This algorithm takes an input (multi)line (or curve) layer, and splits
each feature into multiple parts such that no part is longer then
the specified maximum length.
Supports data-defined maximum length property, and edit in place operation.

The closeEvent approach which was previously used is not reliable
on application exit, so manually force a settings save in this case too.
Avoids loss of command history when closing QGIS
Also remove the manual "Save" history action, as it's redundant
