[mapserver-dev] SVG symbols with modifiable parameters

[Flavio Hendry]

Hi Steve and Tamas

Me again, one more thought ... I am a big fan of MapServer VECTOR 
Symbols, with underestimated potential :-) ... There I can do almost 
anything, except "circular segments" (sure, could be done with a zillion 
of POINTS).

see https://nodi.mapplus.ch/vector.png
and https://en.wikipedia.org/wiki/Circular_segment

In the sample, all symbols except 2 and 4 four from the left are VECTOR 
types, some with STYLE combinations.

2 could be done in such a way:

SYMBOL
NAME 'aw kappe'
TYPE ELLIPSE
FILLED true # or false, can be handled with STYLE
    POINTS
     1 1
    END
    ANGLE 0 # horizontal
    THETA 60 # central angle
    CLOSED true
END

the two parts of 4 could be done in such a way (afetr that STYLEs with 
OFFSETs:

SYMBOL
NAME 'aw benzin_left'
TYPE ELLIPSE
FILLED true # or false, can be handled with STYLE
    POINTS
     1 1
    END
    ANGLE 0 # horizontal
    THETA 60 # central angle
    CLOSED false # vertical line
END

SYMBOL
NAME 'aw benzin_right'
TYPE ELLIPSE
FILLED true # or false, can be handled with STYLE
    POINTS
     1 1
    END
    ANGLE 180 # horizontal
    THETA 60 # central angle
    CLOSED false # open, no vertical line
END
