 | 
						|
Class used to render QgsLayout as an atlas, by iterating over the features from an associated vector layer.
 | 
						|
 | 
						|
QgsLayoutAtlas implement the QgsAbstractLayoutIterator interface, allowing them to be used
 | 
						|
directly with QgsLayoutExporter to automatically output all pages from the atlas.
 | 
						|
 | 
						|
For QgsPrintLayout layouts, it is not necessary to manually construct a
 | 
						|
QgsLayoutAtlas object. Instead, the atlas attached to the print layout
 | 
						|
should be used. This can be retrieved by calling :py:func:`QgsPrintLayout.atlas()`
