[Tilesathome] Experimental Batik Support

[Gert Gremmen]

Finally I am able to test the batik in t at h

Got an error about 

"cannot load AWT toolkit"


I followed the batik installation instructions,
and that seems ok.

Any Clue ??


Regards,

Ing. Gert Gremmen


Thanks Damien,

I am getting the same thing, I will look into it. I haven't seen that on
any other tile.

Regards,
Brent.
