|
The :py:class:`QgsMapSettings` class contains configuration for rendering of the map.
|
|
The rendering itself is done by :py:class:`QgsMapRendererJob` subclasses.
|
|
|
|
In order to set up :py:class:`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.
