* [server] Fix layer order rendering when layers are in groups
Fixes#20810
* Update test images
* [server] Fix order of layers in subgroups
basically: layers in WMS is specified in a comma separated
list where leftmost layer is drawn first (it's at the bottom)
and QGIS layer order is exactly the opposite: first layer
in the TOP (topmost) is drawn last (it is at the top).
For this reason the server reverses the list before passing
it to the renderer.
* Fix order of layers in test
* Update src/server/services/wms/qgswmsrenderer.cpp
This feature allows other layout items (such as scalebars,
north arrows, inset maps, etc) to be marked as a blockers for
the map labels in a map item. This prevents any map labels from
being placed under those items - causing the labeling engine
to either try alternative placement for these labels (or
discarding them altogether)
This allows for more cartographically pleasing maps -- placing
labels under other items can make them hard to read, yet without
this new setting it's non-trivial to get QGIS to avoid placing
the labels in these obscured areas.
The blocking items are set through a map item's properties, under
the label settings panel. The setting is per-map item, so you can have
a scalebar block the labels for one map in your layout and not others
(if you so desire!)
There is still an old issue: views are only available
through DB manager.
Fixes#20674 - again
- Life is really simple, but we insist on making it complicated.

should show partial labels
Layout map items no longer respect the default project setting
for "show partial labels", and instead have their own, per map
setting for this option. (Under the map item properties,
labeling settings button).
The map item setting always defaults to off (unlike the canvas
setting, which defaults to true for a new project) as layouts
should always default to the settings which produce the highest
quality cartographic outputs.
In general I suspect that most users would always want to avoid
rendering partial labels in layouts, but this setting was
previously so deeply hidden that most are unaware of how to
change it. (And previous discussion about changing the canvas
setting to hide partial labels deemed this default undesirable
for the canvas, where showing even a small part of a label
on the map border can help identify what sits just on/off
the edges of the map)
This setting allows per-map control of how close labels are permitted
to be placed to the map item's edges.
Sizes can be set using mm/inches/pixels/etc, and data defined
label margins are allowed.
Fixes#10314
This controls how close labels are permitted to the edges of the map
item. The labeling engine will then try other candidate positions
in order to avoid placing labels within this margin.
in QgsMapSettings to restrict where labels are allowed to be placed
within.
If set, this overrides the default behavior of allowing labels to
be placed anywhere inside the rendered map extent.
This new class QgsImageCache is the equivalent of QgsSvgCache
but for raster images.
QgsImageCache stores pre-rendered resampled versions of raster
image files, allowing efficient reuse without incurring the
cost of resampling on every render.
Additionally, it offers the other benefits QgsSvgCache has,
such as thread safety, ability to transparently download remote
images, and support for base64 encoded strings.
Instead of converting binary fields to truncated strings, we instead
store their contents as QByteArray values, allowing the original binary
content to be retrieved.
This allows for plugins and scripts to utilise binary fields,
such as extracting their contents.
Contains utilities for retrieving the geotag from images and
for setting an image's geotag.
Working with geotags (before this class!) is super-annoying
and fiddly and relies on either parsing command line tools
or depending on non-standard Python libraries which are
not available everywhere, and often very difficult for users
on certain platforms to get installed and working correctly.
With this class we have stable methods for geotag getting/setting
which are universally available and can be used safely
by plugins and scripts.
render exterior ring or interior rings
This option is shown whenever a simple line symbol or
marker line symbol is used as part of a fill symbol for
rendering polygons.
The default behavior is to render both interior and exterior
rings, but this new setting allows users to set the symbol
layer to render only for the exterior ring OR only
for interior rings.
This allows for symbolisation which wasn't directly possible
before, such as a marker line with markers for interior
rings angled toward the interior of the polygon.
