makeCameraImage()

def lsst.pipe.drivers.visualizeVisit.makeCameraImage	(		camera,
			exposures,
			binning
	)

Make and write an image of an entire focal plane

Parameters
----------
camera : `lsst.afw.cameraGeom.Camera`
    Camera description.
exposures : `dict` mapping detector ID to `lsst.afw.image.Exposure`
    CCD exposures, binned by `binning`.
binning : `int`
    Binning size that has been applied to images.
