[mapserver-users] connect label to features

[Basques, Bob (CI-StPaul)]

All,

My original need for the label lines was for labeling point clusters, I wanted to see a label for each point.  Having said that I understand the reasoning behind the logic we're seeing.  I would suggest that  along with "FORCE TRUE" that some sort of related min-distance (MINLEADERDISTANCE?) type of variable be added directly related to leader lines and when they come on/off by scale, or MINDISTANCE working inside s separate STYLE block (Does it work that way now?) for Leader lines.  I think multiple STYLE blocks came after LEADERs . . . .

    Hi Luca,

    The implemented leader label logic does not turn on leader lines for
    every point or feature.  (I believe this is what is causing the
    confusion, as reported by you and Bob)   I personally could see a new
    parameter in the LEADER object of "FORCE TRUE" being very useful, but
    that would take a champion to file a new ticket
    (https://github.com/MapServer/MapServer/issues), create a small test
    case (use yours, but also include the symbolset and fonts that your
    mapfile references, so a developer can just execute shp2img
    out-of-the-box), and then nudge/test/give feedback throughout the whole
    development process.

    Hope that explains more what is happening.
