General

Feature: New grid decoration annotations font settings

Annotations for the map canvas' grid decoration are now fully customizable including font color, buffer, etc.

Temporal

Feature: Cumulative temporal range setting in temporal controller

Adds a setting in the temporal controller to set the animation temporal range to cumulative. This means that all animation frames will have the same start date-time but different end dates and times.

This is useful is you wish to accumulate data in your temporal visualisation instead of showing a 'moving time window' across your data.

Feature: Add a new "Redraw Layer Only" mode for temporal vector layers

When set to this mode, the layer will automatically be redrawn whenever the temporal range is changed, but no time based filtering will be applied to the features.

This configuration is useful when the layer has symbology settings which vary based on the temporal range. For instance, when a layer is using time-dependent rule-based renderer expressions or data-defined symbology expressions.

This feature was developed by Nyall Dawson

Feature: Add basic temporal handling support for vector layers

This exposes some basic native temporal capabilities for vector layers:

  • Static time range for layer (to match raster layer possibilities), this sets a single static time range that applies to the whole layer. All features from the layer will be shown whenever the canvas time overlaps the layer time range
  • "Single field with DateTime": Allows selection of a single Date or DateTime field from the layer. Features will be shown whenever this field value is within the canvas time range
  • "Separate Fields for Start and End Date/Time": Allows selection of start and end Date/DateTime fields from the layer. Features will be shown whenever the time interval calculated from these fields overlaps the canvas time range

We should consider extending this in future, e.g. to add modes like "start time + fixed duration", "start time + duration from field", "start and end time via expressions", etc.

Some known limitations/inefficiencies:

  • Currently only Date/DateTime fields can be used. This was done to simplify the format handling and avoid the need to worry about string fields with different DateTime formats. In future, we should allow selection of string fields and allow users to enter a custom DateTime format string
  • Unlike the Time Manager plugin approach, the approach taken here is to rely completely on QGIS expressions and feature requests to do the filtering (Time Manager uses layer filter strings and attempts to set a native SQL filter syntax so that filtering is done on the backend). This is intentional because it provides a unified filter approach regardless of the provider used (i.e. we don't need to worry about the different SQL syntaxes used natively by the different providers). The beauty of feature request expression compilation should mean that the QGIS expressions are magically turned into native backend queries, BUUUUUUUUUUUT... because we lack QGIS expression support for DateTime literals, we currently rely on the "to_datetime" expression function and coerce everything through strings. None of the expression compilers handle this function, so currently *all* filtering is done on the QGIS side. We need to add functions for optimised DateTime literal creation and then ensure that the different compilers correctly map these literals across to the backend filter syntax to allow all the filtering work to be done on the database side...

So, currently, performance is much worse with large layers compared to Time Manager (and the exposed feature set is smaller, e.g. no interpolation handling) but the advantage is that we can use the native temporal framework and have vector layers animated alongside mesh and raster layers!

Feature: QGIS Project temporal settings

This feature adds project time settings functionality.

You will be able to set the project temporal range either by using manual input or by calculating it from the current project's temporal layers. The latter can be done by clicking the provided "Calculate from Layers" button.

This implementation sets the stage for adding an animation feature for temporal layers in QGIS.

Here's an example of setting the project temporal range. image5

Feature: WMS-T layers temporal constraints support

This feature adds the ability to constrain WMS Temporal (WMS-T) layers inside QGIS. You will be able to constrain the DateTime range for any temporal layer from WMS-T providers.

This implementation lets the user specify the required DateTime range on the layer from the source tab on the layer properties dialog.

Below is an example of the workflow. image6

Note: For instant point in time requests, specifying a range with equal begin and end DateTime will result into using the specified DateTime instant and not a range.

Symbology

Feature: Raster Layer Contour Renderer

This new renderer draws contour lines that are calculated on the fly from the source raster band. It is possible to set the interval of the contour lines and the symbol used for drawing.

In addition there is support for "index contours" - contour lines with higher intervals, typically drawn with a wider line symbol.

If we generate contour lines on input raster blocks 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.

Feature: Add percentage size unit for Raster Image Marker and Raster fill layers symbology.

According to the Feature Request this patch adds a new percentage (of original image size) value for size units of Raster Image Marker and Raster fill (by nirvn suggestion) layers.

For example a layer contains raster images of various sizes and aspect ratios:

image15 image16

If we use an existing Raster image marker size unit values the layer will look like this (with a normal croc, but huge giraffe):

image17

or like this (with a normal giraffe but tiny croc):

image18

The new percentage value of size units is intended to fix this issue.

Both unit tests "qgis_rasterfilltest" and "qgis_rastermarkertest" were rewritten with a set of new control images for testing the proposed percentage value of size units.

Feature: Add data-defined property to font family/style for font markers

Data-defined properties were added for the font markers' font family and the brand new font style properties. This can come in handy for a number of scenarios, including multilingual context where a data-defined property can avoid duplicating datasets.

Labelling

Feature: Respect HTML colors in labels

When enabled, this option will treat label contents as HTML, and any FOREGROUND COLOR RELATED html formatting options will be respected in the rendered label.

Note: ONLY HTML COLOR TAGS ARE RESPECTED. This is NOT a bug, rather this feature has been designed as a "test of the waters" with HTML formatting in labels, and accordingly only formatting options which do not alter the font shape were considered.

On the plus side, it works correctly with ALL other label settings, including shadows, buffers, curved labels, etc!

Now some pretty pictures:

Feature: Automatic placement of labels outside polygons

This feature adds the ability to automatically place labels outside of polygon features.

This is exposed in a number of ways:

  1. A new placement mode which always places polygon labels for the layer outside the features: image23 image24
  2. When using other polygon placement modes, a new checkbox "Allow placing labels outside of polygons" can be checked to allow labels to be placed outside when it isn't possible to place them inside the polygon: image25 image26

The "allow placing labels outside" checkbox can be data defined, allowing users to either allow outside labels, prevent outside labels, or force outside labels on a feature-by-feature basis.

The placement algorithm is based on a modification of Rylov & Reimer (2016) "A practical algorithm for the external annotation of area features". While Rylov & Reimer propose a horizontal sweep-line based approach for selection of candidate label points, in practice I found that this delivered inferior results (and was slower) then just traversing the exterior ring of the polygon and generating candidate point at regular intervals (especially for narrow, nearly horizontal polygons).

As shown in the islands screenshot above, the outside placement mode works as expected with the "Follow label placement" multiline alignment mode.

Feature: Vector tile layer - part 4 (labeling)

Continued work on vector tile layer implementation.

This adds labeling support for vector tile layers. So far this is just working on qgis_core... GUI support will come next. Labeling uses the same concepts as the rendering of vector tiles: we have a list of labeling styles, each one is defined by sub-layer name, geometry type, filter expression, zoom range and of course label style configuration (QgsPalLayerSettings).

Note there is a "chicken-and-egg problem" with labeling: For vector tiles, we create QgsFields for a sub-layer based on fields that renderer and labeling request, but with labeling it was impossible to get required fields if they were not already available in the expression context (hence some small additions to QgsProperty, QgsPropertyCollection, QgsPalLayerSettings to be able to get required field names by not preparing internal expressions at the same time).

image27

An example how to set the above labeling in Python console:

s = QgsVectorTileBasicLabelingStyle()
s.setLayerName("place")
s.setGeometryType(QgsWkbTypes.PointGeometry)
s.setFilterExpression("rank = 1 AND class = 'country'")
ls=QgsPalLayerSettings()
ls.drawLabels=True
ls.fieldName="name"
ls.placement = QgsPalLayerSettings.OverPoint s.setLabelSettings(ls)
labeling = QgsVectorTileBasicLabeling()
labeling.setStyles([s])
iface.activeLayer().setLabeling(labeling)

Feature: Add control over anchor point for callout on label

This gives users control over where a callout should join to the label text (previously, you only had control over where the callout would join to the corresponding feature geometry).

Choices include:

  • Closest point (previous behavior)
  • Label Centroid
  • Fixed corners: Top left/top right/bottom left/bottom right/etc

Data defined control over the label anchor is also possible.

Helps fix some callout ugliness!

Mesh

Feature: Use only specified dataset group

This feature allows the user to choose the dataset groups that are used. This can be done in the mesh layer properties dialog in the source tab.

A new tree view displays all the available dataset groups from the data provider. The dataset groups can be checked/unchecked and renamed.

This widget also provides buttons to load extra dataset groups from files, to expand/collapse the tree, to check/uncheck all items and to reset the defaults from the provider (for now, only the original name).

Only the checked dataset group will be displayed in the active dataset widget in renderer settings.

Feature: Scalar color settings depending on classification

With this feature, MDAL reads classified scalar values in the dataset. When values are classified, the default scalar rendering settings has the color ramp shader and labels set according to the classified values.

Feature: Snap on mesh elements

Adds a method to the API to snap on mesh elements.

The method returns the position of the snapped point on the closest mesh element :

  • For a vertex, the snapped position is the vertex position
  • For an edge, the snapped position is the projected point on the edge, or the extremity of edge if outside the edge
  • For a face, the snapped position is the centroid of the face

The returned position is in map coordinates.

Feature: 1D mesh width/color varying

This feature provides a new way to render a 1D mesh with edge widths that can vary depending on value. So now, width and color vary depending on the value on the edges or on vertices.

The user can define min/max value and min/max width to set the rendering.

For color, the user can define a color ramp shader (as for 2D mesh and raster).

For this new rendering, new generic classes are introduced that could be used outside the mesh framework.

Feature: Support for multiple mesh (since MDAL 0.5.91)

In addition to updating to MDAL 0.5.91, this feature allows several meshes to be loaded from one file.

The file is parsed and a sub layer dialog is launched using the same logic as for vector or raster layers.

Feature: Plug mesh layer to QGIS temporal framework

image35

Time handling in mesh layer

The time in a mesh layer is defined by :

  • A reference time provided by the data, the project or the user
  • Each dataset is associated with relative times
  • Time extent is defined by the first time and the last time of all datasets
    Reference time :          AT
    Dataset 1 time            o---RT------RT-----RT-----------RT
    Dataset 2 time            o-------RT------RT--------RT
    Dataset 3 time            o--------------------------RT-------RT------RT
    Time extent of layer      o----<---------------------------------------->

    -  AT : absolute time (QDateTime)
    -  RT : relative time (qint64)

The class QgsMeshDataprovidertemporalCapabilities stores the reference time provided by the data and all the relative times of the dataset. This class has the ability to return dataset index from a dataset group index and a relative time since the reference time. The reference time (which can be different than the provider reference time) and the absolute time extent are stored in the class QgsMeshTemporalProperties

The temporal settings in the properties widget are only the reference time and the provider time unit: image36

The default reference time of the layer is set by (sorted by priority):

  • From the data provider if defined in data
  • From the project if defined
  • From current date with time 00h00

The user can change it if he wants.

Rendering principle

The 2D and 3D renderers access the active dataset index from the layer with the time range stored in the QgsContextRenderer and in the Qgs3DMapSettings : Relative time is calculated as the difference between the time range of QgsContextRenderer and the reference time stored by QgsMeshTemporalProperties. The dataset index comes from the QgsMeshDataproviderTemporalCapabilities that maps the relative time with dataset index.

The data are brought from the provider with the dataset index.

Static dataset

There is also the option to set a static dataset, that is to choose a dataset that will be rendered independently of the QGIS time controller. To do that the user can check the check box at the bottom of the temporal page of the properties widget: image37 For now, as it was simpler to implement and allows the required dataset to be chosen directly, the user can independently choose scalar dataset and vector dataset from combo boxes with the time associated for each dataset (relative time for data without reference time). If required, a unique time could be implemented but that could lead to inconsistent results with non synchronous datasets. The static dataset settings are in the temporal page but can be easily put in the source page if wanted.

Feature: Resampling from vertex values to face values

Resampling is available for datasets defined on faces, e.g. the value on vertices is calculated from values on faces.

This feature implements resampling from values on vertices to values on faces using the neighbor average method.

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 always smooth. image38

Feature: Mesh 1D Renderer

Update to MDAL 0.5.90

Initial implementation of Support of 1D elements in Mesh Layers

1D Meshes consist of vertices and edges. An edge connects two vertices and can have assigned data (scalars or vectors) on it. The 1D mesh network can, for example, be used for modelling an urban drainage system.

There are new options to display 1D mesh (edges) in the mesh frame tab image43

Also for data on 1D mesh (edges or vertices) there are new options in the contours tab

image44

Note that not all functionality available for 2D meshes is available, notably

  • Support for Mesh Calculator for 1D meshes
  • 3D rendering of 1D meshes
  • Identify and Plots in Crayfish (will be added later in the following PR)

Some functions are not necessary for 1D meshes, especially

  • Export of mesh contours

This feature was developed by Peter Petrik

Feature: Mesh simplification

As a mesh layer could have millions of triangles, rendering can be very slow, especially as all the triangles are displayed in the view even when triangles are too small to be seen.

For those situations, this feature provides an option to simplify the mesh. Simplification leads to one or more simplified meshes that represent levels of detail. When rendering the mesh, the appropriate level of detail is chosen to provide an adequate rendering depending on the view.

A new tab in the mesh layer properties widget allows the user to change the settings :

  • The reduction factor is used to simplify a mesh; the number of triangles for each level of detail is approximately equal to the number of triangles of the previous level of detail, divided by the reduction factor
  • Maximum mesh resolution: this is the average size (in pixels) of the triangles that are allowed to be displayed; if the average size of the mesh is lower than this value, a mesh with a lower level of detail is displayed, i.e. a mesh with an average size just greater than the maximum mesh resolution.

image45

This feature allows the speeding up of rendering as shown in these tables (result in milliseconds) : image46

3D Features

Feature: Arrows for 3D mesh layer dataset rendering

This feature adds an option for displaying arrows on a mesh layer dataset 3D entity, depending on vector dataset.

The dataset used to render arrows is the one chosen for rendering vectors on 2D rendering.

In the same way, the color of arrows are defined in the 2D rendering settings for vector dataset.

In 3D settings, the user can define the spacing of arrows and if size is fixed or scaled on magnitude.

This spacing setting also defines the maximum size of arrows because arrows can't overlap. image49

Feature: Temporal settings for layout map items

This feature adds a collapsible section to the layout map item widget that allows users to enable and set a temporal range to be used when rendering map content.

The start and end datetime value can be data-defined, which comes in handy when used alongside atlas features.

Feature: Allow sorting attribute table by field not listed in the table

Instead of using the same data model for the displayed and the sorting columns, two data models are now used. They use the same API / base class as they are very similar.

This feature was developed by Denis Rouzaud

Feature: Expose control over layer legend splitting behavior on a layer-by-layer basis

This allows users to manually override the legend's default setting for "split layers" on a layer-by-layer basis, by double clicking a layer in the layout legend panel and choosing whether that layer:

  • Follows the default legend setting for splitting
  • Can ALWAYS be split over multiple columns (regardless of the legend's setting)

or

  • Can NEVER be split over multiple columns (regardless of the legend's setting)

Feature: Allow overriding the default symbol for a legend node

This allows users to (optionally) customise the symbol appearance for a legend node, e.g. to tweak the colors or symbol sizes to better provide a "representative" patch symbol compared with how those corresponding features actually appear on the map.

It's useful for exaggerating symbol widths, or for manually tweaking the colors of semi-transparent symbols so that the colors represent the actual appearance of the symbols when rendered on top of the map content. Or to tweak the marker interval/offset in marker lines so that the markers are nicely spaced in the legend patch.

This feature was developed by Nyall Dawson

Feature: Allow placing manual column breaks in legends

Adds the option when configuring a legend item to place a column break before the item, causing it to be placed into a new column.

This allows user control over the column content, for cases when the automatic column generation doesn't result in the desired results.

Feature: Allow marker items to sync rotation with maps

This allows creation of north arrows from marker symbols, exposing the same options as exist for picture items acting as north arrows.

When a marker acts as a north arrow, the map rotation is ADDED to any existing marker symbol rotation (e.g. if you have to rotate the triangle marker 90% to get it pointing straight up, it will still work nicely in north arrow mode!)

Feature: New item type for marker symbols

Allows marker symbols to be placed directly on layouts, e.g. for manually placing markers over a map item or for creation of advanced custom legends.

Feature: Add numeric formatter "fraction" style

This style represents decimal numbers as vulgar fractions, e.g. "3/4" instead of 0.75.

Options include using Unicode superscript and subscript characters for nicer typography, e.g. ¹⁷/₂₃ (this is the default mode, disabling this option uses the "17/23" format). An option also exists for using dedicated unicode characters for specific fractions (where a unicode character exists), e.g. ½ or ¾.

Ultimately this allows for creation of scalebars with fractional representations of distances, e.g. 0 ----- ½ ----- 1 km (instead of 0 ------ 0.5 ------ 1km)

Feature: Rework picture item UI and behavior

Adds an explicit choice between SVG or raster image sources, which allows us to clean up the configuration panel for layout pictures by hiding options which don't apply to a certain picture source. Also permits us to:

  • Reuse the standard SVG selector tree widget, which loads images in a background thread
  • Uses the standard SVG and image selector line edit, which permits drag and drop of images and exposes options to embed images and link to online sources

Ultimately this is motivated by a desire to allow users to embed images in layouts and layout templates

Feature: Feature browser for preview in expression builder

This adds a feature browser to the expression builder so one can browse features to see the result of the expression image65

A new widget is added: QgsFeaturePickerWidget. For the moment, it's a simple combobox (but inherits widget so we can add a map picker button later on). It behaves the same way than the one in the relation reference widget (an editable combobox).

It relies on the same base model (QgsFeatureFilterModel). A new abstract class QgsFeaturePickerModelBase regroups the logic of the, and the new model is called QgsFeaturePickerModel. Basically the QgsFeaturePickerModel used the feature id to identify the features while QgsFeatureFilterModel use a list of attributes (the foreign keys of a relation). It declutters a bit the former model which was quite...cluttered.

As a side note, I tried to use templates for QgsFeaturePickerModelBase, but since templates cannot be mixed with Q_OBJECT, the alternatives sounded like the code would be less readable.

Tests have been added.

Feature: Add ability to edit, import and export user expressions

A new button is added that allows editing of saved expressions. It is only active when a user expression is selected in the expressions tree. When pressed, it opens a window that allows the currently selected user expression to be edited. Changing the label of the expression makes a copy of the currently existing one. Demo

Import/Export

A new button with a menu is added, that allows the import/export of user expressions to/from a JSON file. Clicking on either of the menu entries opens a file selector dialog for the expressions JSON file source/destination. In the case of label conflicts, an additional dialog asks how to proceed - either to overwrite or to skip the current expression. Import/Export Demo

Digitising

Feature: Dedicated avoid geometry intersection/overlap mode

This version of QGIS comes with a new dedicated avoid geometry intersection/overlap mode setting when digitizing features.

| The three available modes are:

|

Allow intersections/overlaps

|

Avoid intersections/overlaps on active layer

|

Avoid intersections/overlaps on user-defined layers list.

|

The third mode's layers list is setup by the user via the advanced snapping configuration widgets.

Feature: New snapping modes: Centroid and middle of a segment (midpoint)

This feature is aimed at improving snapping modes in QGIS by getting closer to the experience of CAD tools.

It adds two new modes. Snapping on the center of a geometry (centroid) and the middle of a segment.

To allow the selection of these new modes, several snapping modes can be selected at the same time.

image67

The order of preference for snapping is as follows: - Vertex, Intersection - Middle - Centroid - Edge - Area

Feature: Snapping to the currently digitized feature

Snapping can now also supports snapping to the feature currently being digitised. This option is enabled/disabled a new button in the snapping toolbar.

This enables some really nice CAD-like editing abilities, such as closing features at a 90° angle or precisely aligning segments inside a feature. It's very efficient once one is accustomed to using the alt+a shortcut to lock the angle.

Feature: Get current parent form values in child forms

This feature adds the option of using current values from the "parent" form in filter expressions (for now only in value-relation widgets: to be used in drill-down filters).

A new "parentForm" scope was added as well as a new set of functions and variables to access the parent from within an embedded child form. The new functions and variables were modelled on the existing "current_value", "current_feature" etc.

The new functions and variables are also available when the parent form is opened from a new (unsaved, unbuffered) feature, making it easier to create drill-down filters based on the parent's values when adding children from an unsaved parent form.

Analysis Tools

Feature: Network logger - more functionality

Adds some more useful tools to the network logger:

  • Copy URL
  • Copy request as JSON
  • Save log to file (after a big warning to users that the log may contain sensitive information and should be treated as confidential)

This feature was developed by Nyall Dawson

Feature: Inbuilt network logging tool

This tool, which is available from the new F12 "dev tools" panel, is a native port of @rduivenvoorde's network logger plugin.

It shows a list of ongoing and completed network requests, along with a whole load of useful detail like request and reply status, headers, errors, SSL configuration errors, timeouts, cache status, etc.

Also has loads of polish and useful capabilities, such as the ability to filter requests by URL substrings and status, and you can right-click requests to open the URL in a browser or copy them as a cURL command.

Why do we want this as a native tool instead of a plugin? Well:

  • It's extremely useful, so is nice to have available out-of-the-box
  • By moving it to c++, we can startup the logging process much earlier than a plugin gets the opportunity to. This allows the log to include additional information, such as requests fired off by other plugins which occur before the network logger plugin has been loaded (also other in-built requests, e.g. news feed)
  • Performance has been an ongoing struggle with the Python plugin. While this is about as close as a 1:1 port as you can get, the performance issues have all been magically solved. The classes have some very intensive list operations, which is likely the cause of the poor performance under Python.

No more illogical ordering like showing a field choice before the layer choice it's based on!

This feature was developed by Nyall Dawson

Feature: Defer model validation

Instead of forcing all child algorithms to be immediately valid and have all parameters correctly filled, this feature defers model validation until run time or when a new "Validate model" action is triggered.

A common frustration with the QGIS model designer is that it constantly forces models to be valid, even work-in-progress models. This means it’s impossible to add a component to a model and only partially populate its settings — you have to fill in everything upfront. If you realise mid way through this that you need to make a change somewhere else in your model, it’s impossible to do without canceling and losing all the settings you’ve already configured.

This change sees the model validation deferred until run time. Models can be temporarily invalid (e.g. having algorithm components which are only partially configured). The missing required values can now be filled at a later stage, without losing any existing settings. If a non-valid model is run, the user gets a descriptive warning informing them of the changes they need to make in order to finish configuration of the model.

This feature was developed by Nyall Dawson

Feature: Added support for different raster data types in Create constant raster layer algorithm

With this feature we added a new advanced OUTPUT_TYPE parameter for the Create constant raster layer algorithm. Via this parameter, you can now specify an output data type for your constant raster layers.

  • Byte
  • Integer16
  • Unsigned Integer16
  • Integer32
  • Unsigned Integer32
  • Float32
  • Float64

Feature: Added Round raster algorithm

With this new processing algorithm we enable QGIS to round Raster values.

The main functionality of the algorithm is either standard up/nearest/down-rounding of floating point cell values or rounding to powers of a user specified base n. The algorithm can be used with rasters of all types (even byte/integer rasters when rounding to powers of n) and outputs the same raster data type. A standard floating point rounding of an integer raster will copy it and raise a warning.

The example shows an output raster rounded to multiples of 10

Feature: Allow running algorithms directly on database (and other non-disk) sources without loading into projects first

This change allows users to directly browse to non disk-based layer sources for any processing feature source inputs. It allows these inputs to be taken direct from postgres, sql server, oracle, wfs, afs, etc layers directly without having to first load them into a project!

We take full advantage of the QGIS browser to enable this:

  • The ability to override on a per-input basis the global processing option for how to handle invalid geometries. Now you can safely leave the default processing setting at the conservative "Stop algorithm execution when a geometry is invalid" setting while easily temporarily overriding this for one particular input!

Feature: Add "filter by geometry type" and "filter by layer type" algorithms to processing

This update adds two new algorithms to processing:

  • "Filter by geometry type": This algorithm filters features by their geometry type. Incoming features will be directed to different outputs based on whether they have a point, line or polygon geometry. It allows for model creation which responds to different input layer geometry types by applying different logic depending on the input geometry type.
  • "Filter by layer type": This algorithm allows conditional model branching based on an input layer type. For instance, it allows a model to adapt to the actual layer type of a generic "map layer" parameter input, and decide which branch of the model to run as a result.

It also adds in the required API to allow algorithms to "prune" model branches based on their calculated results. For example, a model which returns the new FlagPruneModelBranchesBasedOnAlgorithmResults flag will cause any remaining parts of the model which are dependent on the outputs of that algorithm to be entirely skipped IF the algorithm does not return that particular output. (This is a prerequisite component for a future generic "conditional branching by expression" algorithm, and also used by "filter by layer type" to control the model flow based on the input layer type)

Feature: Remember parameter values between model designer runs

When designing a model, users typically will need to run the model many times as they tweak its structure.

This change causes the parameters used when running the model from the designer to be remembered and saved into the model, so that each time you run the model from the designer you don't have to re-set all the input parameter values to the desired test ones.

Makes iterative model design SO much easier!

The resulting dataset will not contain any NoData cells.

Feature: Allowing saving outputs direct to more database formats (and other nice stuff)

This update allows users to save processing vector outputs directly to more database formats.

Previously outputs could only be written directly to postgres databases. With this change, this functionality has been made more flexible and now supports direct writing to any database provider which implements the connections API (currently postgres, geopackage, spatialite and sql server)

Ultimately this exposes the new ability to directly save outputs to SQL Server or Spatialite databases (alongside the previous GPKG+Postgres options which already existed)

(As soon as oracle, db2, ... have the connections API implemented we'll instantly gain direct write support for those too!)

We do this via a nice inline version of the new "new database table name" widget.

Other nice stuff includes:

  • You can now drag and drop file or folders from explorer or the qgis browser to output parameters in order to easily overwrite these files (or save to the folder), matching the behavior possible with inputs
  • You can actually write scripts which output direct to ANY qgis data provider (including oracle and db2)... it's just that these don't get exposed in the UI because they don't yet support the connections API

  • QgsVectorTileRenderer - base class for renderer class implementations for vector tiles
  • QgsVectorTileBasicRenderer - default renderer implementation

New private classes (may be added to public API if needed):

  • QgsVectorTileLoader - handles fetching of tiles from network / mbtiles
  • QgsVectorTileMVTDecoder - handles decoding of raw tile data to features
  • QgsVectorTileLayerRenderer - takes care of overall rendering (fetch + decode + draw)
  • QgsVectorTileUtils - various useful functions

Some new classes that may be shared by vector and raster tiles:

  • QgsTileXYZ - position of a tile in tile matrix set (zoom level, column, row)
  • QgsTileRange - rectangular selection in a tile matrix (start/end column and row)
  • QgsTileMatrix - description of a tile matrix (map extent, zoom level, scale, number of rows/columns)

(also QgsTileMatrixSet to be added later when we support other tile matrix sets than just GoogleCRS84Quad)

Testing

You can load a vector tile layer from Python console, e.g.:

ds = QgsDataSourceUri() ds.setParam("type","xyz")
ds.setParam("url", "https://api.maptiler.com/tiles/v3/{z}/{x}/{y}.pbf?key=YOUR_FREE_API_KEY") 
uri = bytes(ds.encodedUri()).decode('utf-8')
vtl = QgsVectorTileLayer(uri, "Vector Tiles Test")
QgsProject.instance().addMapLayer(vtl)

It is also possible to load vector tiles from a local MBTiles file - for "type" use "mbtiles" and for "url" use a local path (e.g. "/home/martin/x.mbtiles").

There is currently no support for labeling.

Feature: Port processing extent parameter to new api, many other improvements

This update ultimately ports the extent parameter to the new c++ api, but along the way it:

  • Refactors the existing gui widget "QgsExtentGroupBox" to move the guts out to "QgsExtentWidget" (allowing it to be used in places where a group box is inappropriate/looks bad). It also adds a new "condensed" mode for the widget, because the default appearance is very space heavy.
  • The new parameter widget utilises this common QgsExtentWidget, so that we remove all the duplicate code which was previously used by the old python wrapper
  • Allows drag and drop of project map layers from the layer tree to a QgsExtentWidget to auto-set the extent to match
  • Allows QgsExtentWidget to be optionally nullable
  • Allows QgsGeometry values to be set for extent parameter values. This is done to aid use of extent parameters with the "precalculated value" mode in models -- you can now use all the expression geometry functions to calculate a geometry and the bounding box of this is used for the parameter value in the child algorithm

Feature: Interface and API for unified development/debugging tools

Adds interface hooks to allow plugins (and c++) to register "development/debugging" tools

These tools appear in a new Development/Debugging Tools dock, and provide a unified handling and place for these tools in the UI.

The intention here is that specialised development/debugging tools will be moved to this common interface, e.g.

  • Network logger
  • First aid style Python local variables inspector
  • Startup time debugging tools
  • Layer load and rendering time debugging tools ... ?

Here's an example demo showing a "Python locals" dev tool:

Feature: Data type support for QgsProcessingParameterMapLayer

Allow the definition of accepted layer types for QgsProcessingParameterMapLayer. This is useful when an algorithm can work with different layer types (for example, points and rasters) and avoids duplication of the same algorithm with different inputs.

This is an API improvement and is not visible for the vast majority of users.

Feature: Add processing parameter types for database schema and table name

Replaces the previous ad-hoc Python postgis widget wrappers with proper first class c++ dedicated parameters for schemas and tables, with wrappers built off the core connections api.
