[Qgis-developer] Batch generation of map images with MTR

[Richard Burkmar]

Many thanks for all the help. Before I got the responses, I found a way to
make it work, but I'm clearly not working with the new paradigm, so I will
revisit it soon. That code looks very neat Nathan. Thanks for the tip about
Atlas Andreas - I will look at that too.

Thanks and best wishes,

Rich
