This allows a range of new possibilities, including:
- models with static outputs for child algorithms, e.g. always saving
a child algorithm's output to a geopackage or postgres layer
- models with expression based output values for child algorithms, e.g.
generating an automatic file name based on today's date and saving
outputs to that file
These are a visual guide, allowing designers to create logical groups
of algorithms relating to a single task ("eg 'Prepare data')
The title and color of the group boxes can be customized
This algorithm saves the contents of the execution log (right up to
the point in the model at which the 'save log' algorithm executes)
to a file.
It can be used to automatically store the debugging log when running
models for later reference and transparency.
This new renderer draws contour lines that are calculated on the fly
from the source raster band. It is possible to set interval of contour
lines and symbol used for drawing.
In addition there is support for "index contours" - contour lines
with higher interval, typically drawn with a wider line symbol.
If we generate contour lines on input raster block with the same size as our
output raster block, the generated lines would contain too much detail.
This detail can be reduced by the "downscale" factor - this will request
lower resolution of the source raster.
to a single string
We need this to allow processing inputs to load non gdal/ogr/mdal sources, such
as being able to directly read postgis layers without loading them into a project first
- added new `QString QgsField::displayType( const bool showConstraints = false )` to unify the display of field types whenever length or precision are present
- added new argument `expression` to `QgsFieldModel::fieldToolTip( const QgsField &field, const QString &expression = QStringLiteral() )`. Now the tooltip shows "<alias> (<field>)\n<type>\n<comment>\n<expression>" with appropriate formatting
- added meaningful field tooltips in the "Identify Results" dialog
- field tooltips show the same content in "Feature Attributes" form, "Attribute Table" and "Identify Tool"
Fixes#15144
[FEATURE] Implements resampling from values on vertices to values on faces with the neighbor average method. (note that resampling method for datasets defined on faces, e.g., the value on vertices is calculated from value on faces was added in the previous QGIS release)
The default method is set to "none" for resampling from vertices to faces and to "neighbor average" for resampling from faces to vertices. Then the default rendering is now always smooth.
fixes#33978 Allows user to color the mesh layer vector dataset (arrow, stream lines, traces) with color ramp shader depending on the magnitude of the vector.
