and add option to manually set the full extent for a project
This extent will be used instead of the extent of all layers
when zooming to full map extent. It's useful when a project contains
web layers/national layers/global layers yet the actual area of
interest for the project is a smaller geographic area
In horizontal mode left/right,pageup/pagedown changes active slider position
while up/down flips between selecting the upper, lower or range control
In vertical mode up/down/pageup/pagedown changes the active slider position
while left/right flips between the subcontrols
Allows for map renders to be filtered by a z or elevation range,
such that only parts of the layer which are considered within
this range will be rendered.
Implements https://github.com/qgis/QGIS-Enhancement-Proposals/issues/201
*Requires support for respecting the QgsRenderContext zRange to be added
to the relevant map layer renderers
band in build vrt algorithm
Creating a multi-band vrt is much less common vs creating a mosaic
style vrt, so set the default to the most common use case
and most predictable outcome.
value of a parameter for the GUI only
This allows us freedom to change the default settings for an algorithm
shown when opening the algorithm in the toolbox/batch/model without
changing the underlying default value used for the parameter in the
raw API (which we can't do easily without potentially breaking 3rd
party scripts/plugins)
If set, this extent will be used when zooming to full extent (or for the
full extent for a map overview frame) instead of the extent calculated
from all map layers.
The intention is to eventually allow users a way to manually set their
desired "area of interest" for a project, so that zooming to full extent
won't zoom all the way out when the project contains global or national
datasets...
Allows users to select a list of fields to keep, and all other fields
will be dropped from the layer. Helps with making flexible models where
input datasets may have a range of different fields and you need to drop
all but a certain subset of these
Try to remember/set last timeframe (upon timestep- or timeframe-changes).
Setting the stepsize to a different size, did reset the slider to start
(aka timeframe 0).
Same when you changed the range (data time) extent.
This commit tries to set the slider to the same position as before the
step change, if possible). Else it will take the position of the timeframe
in which the start of the old timeframe fits.
fixes#39994
While it was possible to set the opacity for individual symbol layer
colors via data defined expressions, it's so far been impossible to
set a data defined expression to control the overall symbol opacity.
This commit fixes that omission...
