Detailed Description

Class used to render an Atlas, iterating over geometry features.

prepareForFeature() modifies the atlas map's extent to zoom on the given feature. This class is used for printing, exporting to PDF and images.

Note: This class should not be created directly. For the atlas to function correctly the atlasComposition() property for QgsComposition should be used to retrieve a QgsAtlasComposition which is automatically created and attached to the composition.
