Do you have some sample data to play with?

Subject: [mapserver-dev] Label placement issue


It looks like the label placement it not working very well if we need to place labels on polygons that are long thin rectangles orientated on an angle. See the attachment as an example, where each polygon should have a single label at the center of the polygon.

The problem is related to the implementation of msPolygonLabelPoint in mapprimitive.c<https://github.com/mapserver/mapserver/blob/branch-7-0/mapprimitive.c> where some kind of adjustment is happening when the label falls near to the polygon boundaries.

Do we have a workaround to this problem or shouldn't we have an option to switch this correction off in the label definition?

Best regards,
