> renderer = canvas.mapRenderer()
> composition = QgsComposition(renderer)
> composition.setPlotStyle(QgsComposition.Print)
> composition.setPrintResolution(300)
> composition.setPrintAsRaster(True)
> map = QgsComposerMap(composition, 5, 5, 200, 200)
> map.setNewExtent(canvas.currentLayer().extent())
> composition.addItem(map)
> c = iface.createNewComposer()
> c.setComposition(composition)

> Any ideas what can be wrong? Maybe I miss something obvious?
