[Mapserver-users] annotating multiple inline features

[Dylan Keon]

Yeah, I call drawLabelCache() right before saveWebImage().

That bug report from the 3.5 era mentions the shape->draw() method no 
longer takes class index and text string arguments.  The documentation 
hasn't changed, though.  What's the status of shape->draw() in 3.6.x and 
3.7?

Seems like another way to do this might be to add an annotation layer to 
the mapfile, then for each line create a new shape containing one point, 
and use shape->set('text', 'test') to set annotation for that feature. 
I'll give this a shot.  Anyone else tried this?

Thanks,
Dylan
