Changelog for QGIS 3.34¶

Feature: Optional enforcement of "dot" as decimal separator for measure tool¶

A new Always use decimal point checkbox option has been added to the Measure Tool. This option will ensure that measurements and coordinates are copied to the clipboard using a decimal point (dot) separator, even if the current locale uses a comma.

This enables the ability to copy comma-separated (csv) data even in instances where the user locale uses a comma as the decimal separator.

Feature: Show a highlight on identified raster pixels when using identify tool¶

QGIS now displays the geometry of the identified feature result for raster pixels on the map canvas. This matches the existing behavior of the identify tool against vector, vector tile, and point cloud feature types.

This is useful when a identifying a raster which has sections of similar colored pixels and it's difficult to visually determine the exact extent of a pixel.

この機能は Nyall Dawson によって開発されました。

Feature: Show raster row/column of clicked point in identify results¶

When using the identify tool on raster layers, the derived results will now include row and column number of the identified pixel.

This feature was developed by Hannes & Nyall Dawson

Feature: Settings for overriding selection color and selection symbol for vector layers¶

New layer rendering settings allow users to control the color and symbol that will be used in place of the system or project defaults when highlighting selected features.

This setting is defined for each layer and is useful to improve the visibility of selected features by the application of an explicitly defined symbology.

This is useful in various scenarios, including instances where:

• The layer uses a symbol color or style that matches the selection symbology, resulting in the feature selection not being visible

• A line layer uses a thin symbol, and coloring selected lines does not make them visible enough

• Layers with complex symbology (such as raster/ gradient fills/ lines/ shapeburst with a color ramp) would not have a default selection color applied. In these scenarios, the user can now specify a simpler symbol to use for selected features within the layer.

Feature: Toggle labels for Vector Tile Layers¶

Users can now toggle labels for vector tile layers using the vector tile layer styling panel and the layer context menu in the table of contents of the layers pane, effectively replicating the label toggle capabilities for vector layers.

This functionality is enabled by the addition of new functions to the QgsVectorTileLayer API by replicating the existing functionality on QgsVectorLayer.

Feature: "Sticky" Map Decorations¶

Dynamic map decorations are now rendered to a transparent overlay, preventing re-rendering of decoration objects (such as title or scale bar) during navigation. The QgsMapDecoration now also includes hasFixedMapPosition to fix a decoration to a geographic location.

この機能は Yoann Quenach de Quivillic によって開発されました

Feature: Add map render profiler¶

The debugging/ development profiling tools have been extended with a new "map render" profile (accompanying the existing Startup and Project Load profiles).

Through this tool, users are able to identify pain points in their map rendering and track down exactly which layers are causing long map redraws.

この機能は Nyall Dawson によって開発されました。

Feature: Add choice of two different modes for "Refresh Layer at Interval"¶

When using "Refresh Layer at Interval" on vector layers, previous versions of QGIS would simply redraw the layer (for animations etc.), without refreshing data from the data source.

A new widget is provided which allows users to select the layer refresh options according to their preferred use case:

• "Reload Data": The layer will be completely refreshed. Any cached data will be discarded and re-fetched from the provider. This mode may result in slower map refreshes.

• "Redraw Layer Only": This mode is useful for animations or when the layer style should be updated at regular intervals. Canvas updates are deferred in order to avoid refreshing multiple times if more than one layer has an automatic update interval set.

この機能は Nyall Dawson によって開発されました。

Feature: Allow GPU memory limit configuration¶

Users are now able to configure the GPU memory limit configuration on each layer (previously fixed at 500MB per entity/ layer)

A warning is also displayed when a limit is hit, which should assist in troubleshooting large scenes.

This functionality is useful for users utilizing large 3D scenes which exhaust the available GPU memory resources.

This feature was developed by Martin Dobias

Feature: Add support for boundingbox3d¶

Additional API methods for relevant geometry classes are now available for boundingBox3D and calculateBoundingBox3D, as well as extensions to boundingBoxIntersects methods which will now support checking intersections between 3D bounding boxes.

This feature was developed by Jean Felder

Feature: Select multiple layout items¶

New functionality is provided for handling the selection of multiple items simultaneously from the item list within print layouts.

This also improves the user experience of multi-select existing functionality which is available with visual selections by keeping the item selection synchronized with the items list.

この機能は Yoann Quenach de Quivillic によって開発されました

Feature: Layout Page number reflected in page properties¶

When a layout has more than one page, the current page number will be displayed in the item properties header section using the format page_number/pagecount.

この機能は Yoann Quenach de Quivillic によって開発されました

Feature: Automatically open exported layouts¶

A new "Open file after exporting" checkbox option has been added to the export options for PDF, SVG, and Image output types. When selected this option will attempt to automatically open the output file once the export is completed.

The application used to open the file will use the configured default application on the system based on type (using QDesktopServices::openUrl). This feature will leverage the user settings API to remember the selection for the active user profile.

Feature: Add bearing expression function¶

A new bearing function has been added which computes the bearing angle (in radians) between two points.

The bearing is determined in the given CRS and measured clockwise on the given ellipsoid.

この機能は Andrea Giudiceandrea によって開発されました

Feature: Add "layer_crs_ellipsoid"¶

QGIS expressions now include a layer_crs_ellipsoid layer variable, as well as the crs_ellipsoid property available from the layer_property function. The value returned will be the ellipsoid acronym of the layer CRS.

この機能は Andrea Giudiceandrea によって開発されました

Feature: Improve "avoid overlap" type awareness¶

When digitizing features with the "avoid overlap" option, QGIS has improved the behavior of automatically coercing the feature type and includes more meaningful messages to notify users of the automated behaviours.

An example use case would be the digitizing of a multipart polygon on a singlepart polygon target layer, which cannot be saved. QGIS will now automatically only keep the largest geometry portion, and prompt users to optionally restore the additional features as singlepart polygons.

This prevents the digitizing of "sliver" polygons and frustrations with improper feature types.

This feature was developed by Matthias Kuhn

Feature: Improve save vector features handling for pre-existing files¶

When using the save vector features to file algorithm, QGIS will inform users of the default behavior for handling pre-existing files (file overwrite) and provide the abiltiy to select from a range of alternate behaviors (such as overwrite layer or append new features to existing layer)

This greatly improves the ability for users to manage data using flat file data storage formats such as geopackage, whilst minimizing the risk of data loss or unwanted side effects.

Feature: Maintain relations for copied features¶

New functionality ensures that copied features within the same layer will continue to respect project relationship(s) strength.

When copying features within the same vector layer using the map, attribute table, or the copy/ move feature(s) tool, QGIS will now track any relationship within the opened project and duplicate features with the relations intact.

Feature: Support raster band description¶

QGIS will now show band descriptions in the symbology tab for raster layers, in addition to the band number.

This feature was funded by Summer is getting warmer and warmer.

この機能は Alessandro Pasotti によって開発されました

Feature: Antialias setting for raster tile processing plugin¶

A new "Enable antialiasing" parameter has been added to the "Generate XYZ Tiles" processing tool.

This option will be enabled by default (replicating the current behavior) but allow users to disable the antialiasing of map content.

This feature was developed by ASAI Hitoshi

Feature: Create Grid row_index and col_index fields¶

Fields for the row_index and col_index have been added to the output of the "Create Grid" processing algorithm. The fields are added to all outputs of type point, rectangle, and hexagon.

Field values are integers for which the count begins at 0 and increments from left to right (column index) and top to bottom (row index).

This feature was developed by Valentin Buira

Feature: New 'Calculate expression' algorithm for use in models¶

The new "Calculate expression" algorithm will calculate the results of a QGIS expression and make the result available for use in other parts of the model.

It avoids the need to use the same expression multiple times throughout a model if the same result needs to be used more than once and provides additional use cases (such as generating a static timestamp value for use throughout a model).

この機能は Nyall Dawson によって開発されました。

Feature: Add algorithm to convert content from a GLTF/GLB file to standard vector layer features¶

QGIS now allows the conversion of 3D tile content in GLTF and GLB formats into editable vector feature formats.

この機能は Nyall Dawson によって開発されました。

Feature: Port SAGA "DTM Filter (slope-based)" tool to a native QGIS algorithm¶

The SAGA DTM Filter tool has been ported to a native QGIS algorithm.

この機能は Nyall Dawson によって開発されました。

Feature: Clear recently opened project list¶

A "Clear Recently Opened" action is now listed at the bottom of the Project → Open Recent menu, which will remove every unpinned project from the menu.

An additional context menu is also available to enable the ability to remove individual projects from the recent project list, as well as "pin" and "unpin" items.

The state will be synchronized between the recent projects menu and the QGIS Welcome Page.

Feature: OAUTH2 PKCE Authorization Code¶

An implementation of Proof Key for Code Exchange (PKCE, RFC 7636) has been added for OAUTH2 Authorization Code flows, improving resilience to CSRF and code injection attacks.

This feature was funded by Comune di Roma

Feature: Set processing defaults from QGIS configuration file¶

QGIS now supports the capability to configure the default values for GUI tools within the QGIS Processing framework using parameters specified in the QGIS.ini settings file.

This allows for the configuration of user-specific or organization-wide default values for certain algorithms. For example, to set the default value of the GRID_SIZE (precision) parameter on the intersection algorithm, the following configuration may be added to the QGIS/QGIS3.ini in the active user profile directory root:

[Processing]
DefaultGuiParam\native%3Aintersection\GRID_SIZE=0.01

When a user with this configuration opens the relevant toolbox to execute an algorithm, the default value will be specified for them automatically.

Feature: Add setting to control background color for elevation profile charts¶

This option (available from the new Settings → Options → Elevation tab) allows users to set a specific color to use as the background color for elevation profiles.

This can make the chart more readable for certain datasets, e.g. point clouds with RGB coloring, where the default background color is too similar to point colors to be easily discernable.

This is an opt-in setting, and by default the elevation profiles will continue to display using the standard system background color.

Feature: Discover relations for Oracle provider¶

QGIS now supports the automated discovery of relations for the Oracle data provider.

This feature was funded by Métropole de Lille

この機能は Jacky Volpes によって開発されました

Feature: Drop interactive shell from GRASS C++ Plugin¶

For maintenance reasons, the interactive shell for the GRASS C++ Plugin, as well as the embedded QTermWidget, have been removed from future releases.

It is expected that the GRASS Processing Plugin will be given priority development and maintenance support going forward, and providing an interactive GRASS shell is not a critical functionality for QGIS itself but rather something that users may manage externally.

Further details on the specifics of this feature cleanup can be found on the feature Pull Request.

Feature: Function to export runtime profiler model content as text¶

A new function has been added to allow for the export of the current runtime profiler (QgsRuntimeProfiler) model content as a multi-line text string.
