Chris,
Submit a new bug report to the MapServer Bugzilla under the C library
component. Looks like msSaveMap may need to be updated.

Argh - the map instance keeps this and works fine, but refuses to

it out to the map file:
symbolObj circle =3D new symbolObj("circle", null);
circle.type =3D (int)MS_SYMBOL_TYPE.MS_SYMBOL_ELLIPSE;
circle.filled =3D mapscript.MS_TRUE;
lineObj line =3D new lineObj();
line.add(new pointObj(1, 1, 0, 0));
circle.sizex =3D 1;
circle.sizey =3D 1; =09
map.symbolset.appendSymbol(circle);
later I use:
sty.symbol =3D map.symbolset.index("circle");=09
which works fine - sets the index properly. No symbols get written to
the mapfile, however. Is there something special I need to do to get
the symbols to write out?
Thanks,
Chris

Oh, I see. Yeah, it's possible. Here's an example from one of my =20
Python projects:
circle =3D mapscript.symbolObj('circle')
circle.type =3D mapscript.MS_SYMBOL_ELLIPSE
circle.filled =3D mapscript.MS_TRUE
line =3D mapscript.lineObj()
line.add(mapscript.pointObj(1,1))
circle.setPoints(line)
circle.sizex =3D 1
circle.sizey =3D 1
mo.symbolset.appendSymbol(circle)
The "mo" name is bound to a mapObj. It's very important to get
sizex =20
and sizey right, should be the width and height of the symbol in
the =20
same units as the point and line coordinates used to construct the =20
symbol.
To use this symbol
style.symbol =3D mo.symbolset.index('circle')
Translate this into C# and you should be good to go.
cheers,
Sean

Hi Sean-
Is there a way to accomplish this with MapScript? All I see is a =20
way to
set the symbolset.
Thanks,
Chris

Hi Julien-
Thanks for your response. Here are the contents of the symbol file:
SYMBOLSET
SYMBOL
NAME 'circle'
TYPE ELLIPSE
POINTS 1 1 END
FILLED TRUE
END
END
The problem I'm having is intermittent and I can't reliably
reproduce
it. My only thought was that for some reason mapscript couldn't
read
the file. Is there any way to embed these symbols directly in the
mapfile instead of referencing the symbolset file?
Thanks,
Chris
Yes, just add any SYMBOL block as a child of the top-level map.
