7ba5998db2 Calculate correct legend size when using expression based labels 2019-01-18 20:36:30 +11:00
Nyall Dawson
d70b60d48f [FEATURE][layouts] Allow expressions to be embedded inside legend item text 
This feature allows for expressions to be embedded directly inside
legend item text (e.g. group, subgroup and item text). The expressions
are evaluated at render time, with full knowledge of the legend's
expression context (so can utilise variables from the layout/layout item/
etc)

There's no UI for this yet (that will come in 3.8), but expressions are
entered using the standard [% 1 + 2 %] format.

E.g. a legend item text of

    My layer (rendered at 1:[% @map_scale %])

will show in the output as

    My layer (renderer at 1:1000)

b43943a9b0 [FEATURE] New expression variables for legend items 
Adds new variables for use in data defined expressions for layout legend items, including

- @legend_title
- @legend_column_count
- @legend_split_layers
- @legend_wrap_string
- @legend_filter_by_map
- @legend_filter_out_atlas

Additionally, if the legend is linked to a map, then expressions used in that legend will also have access to the linked variables, including @map_scale, @map_extent, etc.

021f5ea366 [needs-docs][api] Rename QgsDistanceArea methods to change "date line" 
to "antimeridian"

Because the date line =/= +/-180 degree longitude, which is what
we were incorrectly using it to mean.

a8bd12c4e3 [FEATURE][API] Add method to QgsDistanceArea to split a (multi)line geometry 
at the antimeridian

Whenever line segments in the input geometry cross the antimeridian, they
will be split into two segments, with the latitude of the breakpoint being
determined using a geodesic line connecting the points either side of this
segment.

If the geometry contains M or Z values, these will be linearly interpolated
for the new vertices created at the antimeridian.

geometry types, instead of silently returning empty lists

eaad71e0c9 Tweak API 
Better to use QVector here, because the QgsLineString/QgsGeometry
methods all use QVector too, and we want to avoid unnecessary
list->vector conversions.
