(e.g. parameters) when they are run in the "edit in-place" mode
This allows algorithms to dynamically adapt their behavior to make them compatible
with in-place mode. Previously, some useful algorithms could not be
run in-place because they alter a layer's structure (e.g. adding new
fields).
Now, these algorithms have a means to detect that they are being
run in-place and change their input parameters accordingly. E.g.
an algorithm which usually adds new fields to store calculated
values (such as "add xy fields to layer") could instead expose
field parameter choices to ask the user to pick from existing
fields in which to store the calculated values, thereby avoiding
the need to change the table structure and making them eligable
for running in-place mode.
Note that this needs to be handled algorithm-by-algorithm, it's
not automatic! It's just the raw api to allow this...
update any open configuration panel to reflect the new format
(or dismiss it automatically if the new format is invalid)
Avoids UI going out of sync with text formats when a panel is already
open
This algorithm calculates the rotation required to align point features
with their nearest feature from another reference layer. A new field is
added to the output layer which is filled with the angle (in degrees,
clockwise) to the nearest reference feature.
Optionally, the output layer's symbology can be set to automatically
use the calculated rotation field to rotate marker symbols.
If desired, a maximum distance to use when aligning points can be set,
to avoid aligning isolated points to distant features.
Designed for use cases like aligning building point symbols to follow
the nearest road direction!
in simple line symbol layers
New options are:
- Align dash pattern to line length: If checked, the dash pattern lengths
will be subtely adjusted in order to ensure that when a line is rendered
it will end with a complete dash element, instead of a gap element or
partial dash element
- Tweak dash pattern at sharp corners: If checked, this option dynamically
adjusts the dash pattern placement so that sharp corners are represented
by a full dash element coming into and out of the sharp corner. It's designed
to better represent the underlying geometry while rendering dashed lines,
especially for jagged lines
[FEATURE] Introduces mesh virtual datasets
With the mesh calculator the user can choose to create those "virtual" dataset groups that will be added to the layer. Then, for these dataset groups, values are not stored in memory but each dataset is calculated when needed whit the formula entered in the mesh calculator.
Those virtual dataset groups are saved with the project.
If needed, the user can remove them or can persist them on files to make them persistent.
