Re: [Matplotlib-users] Placing images on figures

[Eamon C. <eam...@gm...>]

Thanks for the suggestion!

The reason my initial attempts failed was because I (erroneously)
assumed that the default axis spanned (0, 0), (1, 1). Now I that I
know better, I can place an axis for each image in the right place and
everything looks fine.

However, I'm still interested in knowing how to query the pixel size
of the figure, so I can translate normalized axis coordinates to pixel
coordinates.
