Re: [Matplotlib-users] EMF export doesn't work

[Michael D. <md...@st...>]

Unfortunately, the EMF backend is no longer maintained.  We had 
discussed removing it well over a year ago, and I actually thought it 
had been removed, but obviously it wasn't.

It needs someone to port it to the new backend API introduced in 0.98.x 
and to maintain that code.  When quite some time ago, there really 
wasn't much interest in doing that.  I would be happy to help someone 
with the details involved, but don't have the time myself at the moment.

Sorry for the confusion -- what do other developers think?  Should we 
remove the backend and document the change, at least for the time being?
