method when exporting layouts to PDF
Options are for Lossy compression, which is the default JPEG compression
used, and Lossless compression (which creates bigger files in most
cases, but is much more suitable for professional printing outputs
or for post-production in Illustrator/etc)
The Bad news: this option is available in builds based on Qt 5.14
or later.
This feature allows users to enable map clipping for layout map items
so that the maps are clipped to the boundary of the current atlas feature.
(It's available for polygon atlas coverage layers only, for obvious reasons!)
Options exist for:
- Enabling or disabling the clipping on a per-map basis
- Specifying the clipping type:
- "Clip During Render Only": applies a painter based clip, so that
portions of vector features which sit outside the atlas feature become
invisible
- "Clip Feature Before Render": applies the clip before rendering features,
so borders of features which fall partially outside the atlas feature
will still be visible on the boundary of the atlas feature
- "Render Intersecting Features Unchanged": just renders all features
which intersect the current atlas feature, but without clipping their
geometry
- Controlling whether labels should be forced placed inside the atlas feature,
or whether they may be placed outside the feature
- Restricting the clip to a subset of the layers in the project, so that
only some are clipped

Allows for tweaking the positioning of dashes/spaces in the line, so
that the dashes/spaces can be placed at nicer positions to account
for corners in the line (also can be used potentially to "align"
adjacent dash pattern borders)
Offset can be set in different units, including map units, and can
be data defined
Unlike QgsGeometry::asQPolygonF, this allows for correct handling
of multipolygons and rings, etc.
And potentially, the generated QPainterPaths could use arc segments
instead of segmentizing geometries. In fact, there's been disabled
code which seems to do this in place since the new geometry engine
was introduced back in 2.10! TODO: check if this code works correctly...
We don't want labels to be positioned using unclipped feature
geometries, rather we want them to be positioned nicely on the
visible portions of features
Offers the same functionality as the Random points inside polygons
algorithm, and in addition it includes (possible to opt-out) the attributes
from the containing polygon and the ability to specify a seed for the random
number generator.
Could replace the Python algorithm Random points inside polygons, but
this C++ implementation only supports "Points count" ("number of points
for each feature") directly, while "Points density" is supported by allowing the
point count to be data defined (using the polygon area to calculate the
number of points).
[FEATURE] Introduces memory dataset groups for mesh layer. These dataset groups are temporary and are not kept when the project is closed.
Memory dataset groups can be created from the mesh calculator with a new option.
Allows the possibility to remove or save these memory dataset groups to a file with specified driver.
and still be able to store generic labels on the item (like the field name and the field alias)
This fixes that there has been no example values in the expression builder on the fields when an alias has been used
Now it's possible to get a breakdown of the various stages of
project load, in order to identify the causes of slow project
load times.
TODO: in 99% of cases this will be caused by one or more layers,
so it would be nice to further break down the individual layer load
times, e.g. so that for a WFS layer we see the time taken for
the initial server capabilities queries, etc...
For now, you just get the overall load time of each individual
layer.
The QgsFeature default constructors initialized
feature id to 0, which is a valid feature id
instead of initializing it fo FID_NULL.
This was just wrong and broke the validator for
UNIQUE constraints in case a feature with fid 0
existed in the data provider.
Fixes#36962
