Hi
points style:
shop=car_repair [0x2c14 continue] shop=car_repair [0x2c09]
and a polygon style:
shop=car_repair [0x12]
Processing this on a very simple OSM file containing one polygon tagged shop=car_repair and one point tagged shop=car_repair, using the --add-pois-to-areas switch, I see: One polygon of type 0x12, with a 0x2c09 POI in the centre Two POIs consisting of one of type 0x2c09 overlain on top of another of type 0x2c14
Yes that does appear to be the case.
It might be difficult to change. We don't know if something is a polygon until after the style rules have been run and at that stage it is too late for the normal processing to occur for the generated point. At least that the way it is written - it is possible that it could be changed, if anyone has any ideas please post.

I'm sure I saw an email from WanMil recently that said there already is code in mkgmap that can test to see if an object is a closed polygon.
Yes, it is possible to check if an object is a closed which does not necessarily mean that it is a polygon (example: roundabout). But we could add some methods (maybe they already exist) that can check if an object is tagged with polygon tags.
If, so, then this code could be re-used and --add-pois-to-areas could be run before the style file processing. Whilst I'm helpfully palming off work to others more skilful than myself, could whoever does this also add some logic to make sure the resultant POI is always placed *inside* the polygon? :)
Do you have an algorithm that performs within an acceptable time?
