Hi Rosario,
Sorry for my late answer.
First, I suggest to use RTMetricMap instead of RTMapBuilder. Regarding your
problem, Roassal does not have a PNG exporter. This is not a big deal to do,
but I just haven’t made it yet. If you want to give a try, and porting it from
Roassal1 to Roassal2, then you are very welcome.
You need to open the view to properly set the extent. I am not quite sure why
and how this happens. I have to dig this out. But again, it would be easier
with the PNG exporter.
Anyway, I think you want to do the following:
-=-=-=-=-=-=-=-=-=-=
| b |
b := RTMetricMap new.
b countries: RTMapBuilder countries color: Color white.
b open delete.
b view canvas morph
extent: b view canvas camera encompassingRectangle extent;
exportAsPNG.
-=-=-=-=-=-=-=-=-=-=
Let me know how it goes.
Oh, and by the way… the work you are doing with the tweets is truly amazing.
Will you be at Esug?
Cheers,
Alexandre
