Allows the full range of formatting options exposed through
text renderer - e.g. scalebar text with buffers, shadows,
background shapes, letter spacing, etc.
Say goodbye to unreadable scale bar text!
Adds geometry methods to create variable width buffers, including
tapered buffers (with a specified start and end diameter) and
variable width buffers from line string m values.
Also adds processing algorithms which expose these methods
to processing.
This allows users to optionally set a sort order to use when
assigning values in the Add Incremental Field algorithm.
Previously values were always added using the original feature
order. With this change users can control the order in which
features are assigned values.
Finally starting a suite of unit tests for overlay algorithms:
- overlay1 - layers that cover various basic overlay situations
- overlay2 - layers where one input has self-intersecting polygons
- overlay3 - layers where intersections return different geometry types
Aside from the performance benefits, the Python version of this
algorithm occasionally fails on Travis with odd errors. Hopefully
by porting to c++ it will fix these, or at least give useful
debug information in the event of a fail.
Also add support for curved input geometries.
- Output interpolated points when travel cost falls mid-way along
an edge
- Output all intermediate reachable points also
- Make outputting upper/lower bound points optional, and non-default.
Now by default we just output all definitely reachable points and
the interpolated points along edges which correspond to the travel cost.
This allows the output to be used to correctly generate service areas
e.g. by concave/convex polygons and all reachable nodes will be
included in the area.
- Allow algorithm to optionally output a line layer (and make the
point layer optional too, and default to just the line layer output)
containing all reachable line segments (including interpolated
segments of lines when the travel cost sits midway along that
edge). This output is more easily understandably for users.
