Sorry, for some reason I was thinking that image_rotate was python. Have
a look at pr2_camera_synchronizer. It is big and messy, but the
reconfigure part is pretty simple. Look at
src/pr2_camera_synchronizer/synchronizer_classes.py

Relevant lines to your question:
   from pr2_camera_synchronizer.cfg import CameraSynchronizerConfig as
ConfigType
   self.server = DynamicReconfigureServer(ConfigType, self.reconfigure)
