[mapserver-users] Angle Follow will accept only simple linestring don't MultiLinestring ?

[Andrea Peri]

The two label are at different max/min scaledenominator.
The goal is to have little label size at low scales and bigger font size at
bigger scales.

However only one lable is active at one scale level.

Is this incompatible with "follow" ?
