symbology, and add checkbox to disable this in their elevation
properties page
This means that vector results in elevation profile charts will default
to showing features using their corresponding 2d renderer, allowing
eg categorized classes to be visible on the profile chart. (In the
case that a profile symbol type doesn't match the layer's renderer
symbol types, we just take the symbol color from the renderer)
Users can now indicate that a symbol should be treated as a animated
symbol, through the new "Animation Settings" option in the symbol
widget's Advanced menu.
This settings panel allows users to enable animation for the symbol
and set a specific frame rate at which the symbol should be redrawn.
When enabled, the @symbol_frame variable can be used in any
symbol data defined property in order to animate that property.
For instance, setting the symbol's rotation to the data defined
expression
@symbol_frame % 360
will cause the symbol to rotate over time. (with rotation speed
dictated by the symbol's refresh rate)
Instead of always defaulting to 100mb, then base the cache size
on the system memory:
- > 32gb, use 500mb
- 16-32gb, use 250mb
- else 100mb
The larger sizes can make a big difference to rendering speed for
complex projects, so let's let powerful systems utilise all that
memory!
(Only supported on linux for now)
This new marker symbol type allows points to be rendered using
an animated marker, sourced from an animated gif, webp or mng
animation.
Options are present for marker file, size, angle and frame rate.
There are two ways in which animated symbols are handled:
1. If the map itself is considered an animation, then the frame
rendered for the animated marker is based on the map animation
frame and frame rate. This is the case when the temporal
controller is set to the Animation mode. In this case the
animated markers will follow the temporal controller animation,
e.g. pausing when the animation is paused, advancing frames
with the animation, etc. The map will also be redrawn using
the frame rate set for the temporal animation.
This mode also applies when exporting an animation from the
temporal controller.
It's also the mode used when a plugin specifically sets the
frame rate and current frame QgsMapSettings properties, so
e.g. @timlinux's QGIS Animation Workbench plugin will dictate
the marker animation frame to render.
2. If the map is NOT considered an animation (i.e. it's just
a plain old normal QGIS project), then the frame to render
will be based on the current timestamp alone.
Markers will be animated when their corresponding layer is set
to a temporal mode, and a temporal animation is playing.
