[Qgis-developer] Geometry modifiers for labeling

[Andreas Neumann]

Hi Matthias,

You mean I should then set the data-defined label position to the start 
and the endpoint of the line?

Yes - this kind of works, but I would have to calculate the 
orientation/direction of the first and last segment of the line myself.

But we are getting closer to solving this issue ;-) ...
