[Bioperl-l] new to the group. And a quick demo of SVG::GD

[Ronan Oger]

Hi Todd,

I see we're both running into the same problems. In particular the font issue 
(this seems to be due to the way perl handles xs objects? it returns an 
object that sometimes seems to bet treated like a string.

Maybe someone in bioperl has advice about how to grab the GD namespace without 
forsaking the use of the GD methods?

Pls. see private re. collaboration. I'm all for it.

I've installed your module and will run around in it a bit to get a better 
world view of how you use it and of how much similarity there is between 
SVG::GD and GD::SVG.

For now, feel free to take anything out of SVG::GD for your own use.
