             Detector ID to get image data for.

         imageFactory : `lsst.afw.image.Image`

             Type of image to construct.

         binSize : `int`

         -------

         image : `lsst.afw.image.Image`

             Appropriately rotated, binned, and transformed

             image to be mosaicked.

         detector : `lsst.afw.cameraGeom.Detector`
