Hi
Is it possible to make a symbol of symbols?
My use case is wind barbs. I use lines for barbs up to 45kn, but at 50kn
and above the 50kn flag is a filled triangle.
I try a symbol like this:
SYMBOL
NAME "wind_barb_50"
TYPE VECTOR
FILLED TRUE
POINTS
26 8.2
2 8.2
4.4 0
6.8 8.2
26 8.2
END
END
But here the line of the wind barb is not display.
An example here

( for reference a 40kn wind barb is also plotted)
The line of the wind barb can be displayed if I set outlinecolor ( to
the same color as the color), but then the line is a bit thicker than
the wind bards with no 50kn flag. Example of both here

Example how it should look https://www.weather.gov/hfo/windbarbinfo
I have looked at various variation using a line symbol and a flag symbol
using both in the layer. But then I get problems when I rotate the
symbols. I also have looked at using offset and anchorpoint for the flag
relative to the line. But I can't get it right.
So then my idea of have a line symbol and a flag symbol and then join
them together in a new combined symbol before putting it in a layer.
Any ideas or sections of the manual I have missed?
