How do I get the coordinates in page units (i.e. millimetres) for a QgsComposerMap item?
I can get the upper left coordinate using pos, but can't see any method that provides access to the width and height, or the lower right coordinate.
>>> map_item = composition.getComposerItemById('map')
>>> map_item.pos()
PyQt4.QtCore.QPointF(6.0, 6.0)
To get the width of the map item in millimetres:
map_item.rect().width()
And to get the height of the item:
map_item.rect().height()
