Detailed Description

The QgsMapSettings class contains configuration for rendering of the map.

The rendering itself is done by QgsMapRendererJob subclasses.

In order to set up QgsMapSettings instance, it is necessary to set at least few members: extent, output size and layers.

Some systems use high DPI scaling that is an alternative to the traditional DPI scaling. The operating system provides Qt with a scaling ratio and it scales window, event, and desktop geometry. The Cocoa platform plugin sets the scaling ratio as QWindow::devicePixelRatio(). To properly render the map on such systems, the map settings device pixel ratio shall be set accordingly.

Member Enumeration Documentation

◆ Flag

enum QgsMapSettings::Flag

Enumeration of flags that adjust the way the map is rendered.

Enumerator
Antialiasing	Enable anti-aliasing for map rendering.
DrawEditingInfo	Enable drawing of vertex markers for layers in editing mode.
ForceVectorOutput	Vector graphics should not be cached and drawn as raster images.
UseAdvancedEffects	Enable layer opacity and blending effects.
DrawLabeling	Enable drawing of labels on top of the map.
UseRenderingOptimization	Enable vector simplification and other rendering optimizations.
DrawSelection	Whether vector selections should be shown in the rendered map.
DrawSymbolBounds	Draw bounds of symbols (for debugging/testing)
RenderMapTile	Draw map such that there are no problems between adjacent tiles.
RenderPartialOutput	Whether to make extra effort to update map image with partially rendered layers (better for interactive map canvas). Added in QGIS 3.0.
RenderPreviewJob	Render is a 'canvas preview' render, and shortcuts should be taken to ensure fast rendering.
RenderBlocking	Render and load remote sources in the same thread to ensure rendering remote sources (svg and images). WARNING: this flag must NEVER be used from GUI based applications (like the main QGIS application) or crashes will result. Only for use in external scripts or QGIS server.
LosslessImageRendering	Render images losslessly whenever possible, instead of the default lossy jpeg rendering used for some destination devices (e.g. PDF). This flag only works with builds based on Qt 5.13 or later.
Render3DMap	Render is for a 3D map.
