Hi all,<div><br></div><div>So one of the main reasons why this is so messy, IMO, is that we don&#39;t have a self-describing image.  All we have is a numpy array.  Would it worthwhile to do something like create an ImageArray, which subclasses numpy ndarray? </div>

<div><br></div><div><a href="http://docs.scipy.org/doc/numpy/user/basics.subclassing.html#simple-example-adding-an-extra-attribute-to-ndarray">http://docs.scipy.org/doc/numpy/user/basics.subclassing.html#simple-example-adding-an-extra-attribute-to-ndarray</a></div>

<div><br></div><div>We could then append on things like x-axis, y-axis, optionally things like field names, and who knows what else?  For example:</div><div><div><a href="http://nbviewer.ipython.org/url/hub.yt-project.org/notebooks/2225815c19a844c9974838543f09e267.ipynb">http://nbviewer.ipython.org/url/hub.yt-project.org/notebooks/2225815c19a844c9974838543f09e267.ipynb</a></div>

</div><div><br></div><div>This would significantly help manage the rendering output since we lose info about the image as soon as we lose the camera.  We could additionally write a thin layer to save these images out in hdf5, looping over the info dictionary for attributes.  </div>

<br>
We got an anonymous bug today.  My guess is this is related to the<br>
transpose in write_image.<br>
