As long as the image is not _explicitly_ re-read from disk as in my
example and as long as the image descriptor is not garbage collected,
this should already be the case. Not even clearing the image cache (I
mean the built-in image cache) would cause a second conversion,
because the image descriptor contains all image data as a value of the
:data attribute.
