Hi,
if I want to create a map where South is at the top and North is at
the bottom - how would I best do that? Two approaches I can think of:
1. Invent a custom projection that will do it for me. - Is the whole
proj4 projection support versatile enough for that (even if I wanted to
rotate not by 180 degrees but, say, by 131 degrees)? I haven't yet
bothered to learn to (de)code a proj4 initialization string but if it
has the power to do custom rotations then that would a good reason to
tackle that.
2. Tell Mapnik to render the labels and symbols at 180 degrees angle,
and later rotate the resulting bitmap. - The TextSymbolizer and
PointSymbolizer do not seem to have a rotate option but I figure it
should not be overly hard to add one, or would I likely encounter
difficulties?
Other ideas, experiences?
Bye
Frederik
