I still have the feeling that the cause of the problems with multipolygons may be due to the representation of "polygons with holes" in the img file. If I'm not mistaken, the multipolygon code connects the inner and outer polylines forming the multipolygon which either leads to spurious lines ("triangles", see sea polygons in mp-mode) or to vanishing inner polylines.
Yes that is what it does.
Is this really the correct representation of "polygons with holes" in the img file?
I've no idea, I've been wondering too. It could be that the way Mark is doing the sea/island polygons is the right way, except that if I'm not mistaken his method only works with a TYP file, whereas it is clearly possible to do this without since the MetroEurope maps don't have a typ tile. I am going to look into some examples, if not today then tomorrow. : There is also still a problem with the rendering of polygons with
holes in the polish format. The attached mp-file is displayed correctly
Yes that case is just not implemented as far as I know. Happy 2010 to everybody. ..Steve
