Recently someone committed a fix for labeling that used GEOS intersection to avoid scanning too many segments for candidates. Since GEOS is involved already, it could as well be used for GEOSPointOnSurface on the intersection between the polygon and the viewport. That will give you what you want. Sounds like worth a ticket on the tracker. --strk; () Free GIS & Flash consultant/developer /\ http://strk.keybit.net/services.html ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Short of defining coordinates for my labels, I don't think there is a good answer yet. (In my cases it's usually only a small number of problem fields in a large dataset and I can't convince myself that it's worth the effort.) In one of the datasets that I get a situation like this the objects all have straight sides and I usually put the labelling parallel to the edge of the polygon. Would that work as a work-around? -ramon. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] How should work the placement "over" on adv-label
Hi, I have a situation of polygon like this: - | A | || | | | | B || | ||| | ||| | ||| | ||| | | || - Where the poly A has a hole and the poly-B fill exactly the hole of poly-A I need to have a labeling like this: - | value1 | || | | | ||| | ||| | | value2 || | ||| | ||| | | || - I try with the label-advanced plugin and use the option Placement "Over". But it produce instead this situation: - || || | | | | value1 || | ||| | | value2 || | ||| | ||| | | || - I don't know if this is a wanted result or not for the "over" placement. But I guess this is not the better solution , because don't allow to understand what is the label of PolyA and the label of PolyB.
