[mapserver-users] Re: [mapserver-dev] PostGIS "curvepolygon" support

[Flavio Hendry]

Hi again

My first writing:
As far as I see, this is not supported yet (polygons without curves are 
drawn, the ones with curves not). Any idea if it will be and when. Thanks.

and me again today:
figured out that basically this is supported right now with some SQL in 
the MapFile:

DATA 'wkb_geometry from (select g.gid, ST_CurveToLine(g.wkb_geometry) as 
wkb_geometry from public.mylayer g) as subquery using unique gid using 
SRID=21781'

However, this turns out to be REALLY slow (10 secs for simple map, >20 
secs for complex maps, same data, no arcs 2-3 secs) ... My questions:
- any idea if this could be somehow speeded up?
- as Paul stated: anyone out there with a better idea submitting an offer?

Someone might ask why one wants that: we'd need the arcs for other apps 
accessing the data and we'd like to avoid duplicating the data ...

Mit freundlichem Gruss / Best regards
Flavio Hendry
