Hi list,
I have defined a very nice map with MapNik, which I provide with TileCache.
I used a XML-configuration (based on the
http://trac.mapnik.org/wiki/XMLGettingStarted XMLGettingStarted-Tutorial ).
Now I want to change the output format to a paletted PNG with alpha
transparency using the 'PNG256'-parameter. The filesize of the 32bit PNG is
a bit too big. Where do I have to define it? In the python script, in the
XML or in TileCache?
I tried this:
render_to_file(m, map_output,'png256')
and I added this:
m.save('test.png','png256')
to the python script, but no success. Is it also possible to switch the
renderer from AGG to CAIRO? I also want to experiment with the vector output
formats.
Thanks for your help in advance.
Jürgen
