The image_downsample code is in the repository (bokeh/transforms/image_downsample.py). I saw that in v0.4.1 there was a demo branch which had some example code (remote_ocean_volume.py, http://continuum.io/blog/bokeh-0.4.1). That branch has been deleted. Are there any examples available using image_downsample? I know things have changed with downsample since 0.4.1, as far as using the Blaze server, etc., I’m looking for something simple like serversource.py or blaze_source.py but for image_downsample. It seems I would need to load my data in the blaze config.py file, but I’m not sure what format it should be in (Pandas df?)
