Dashed Outline

[David Fawcett]

As promised, I added a working example to the Wiki

http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?SymbolExamples

Scroll down to the 'Creative Solutions' section.

For documentation in the archives, here is a working example.  Note
that the STYLE object was added in version 4.0, so this example won't
work with pre-4.0 versions of MapServer.

The effect is achieved by adding two styles to the class, one for the
colored fill and the other for the dashed outline.


LAYER
    NAME county
    TYPE polygon
    STATUS default
    DATA cntypy
    CLASS
        STYLE    #this style defines polygon fill color
            COLOR 225 225 185
        END
        STYLE     #this style defines the outline of the polygon
            OUTLINECOLOR 128 128 128
            SYMBOL 'dashed'
        END
    END
END

This example requires that:

    1. You have a symbol definition in your symbol.sym file that is
named 'dashed' and looks like this

    SYMBOL
        NAME 'dashed'
        TYPE ELLIPSE
        POINTS 1 1 END
        FILLED true
        STYLE 10 5 5 10 END
    END

    2. You have line in your MAP file stating the correct path to your
symbols file (e.g. SYMBOLSET symbols/symbol.sym)

Yes,
It is possible. You have to define a new symbol into .symbols file for
a
dashed line.
Then you have to define 2 styles for that class:
- The first one will have the colour for the filling or the symbol for
the interior or the polygon.
- The second style defines the line (symbol, size, colour).
I found out that if I put everything in one style, the symbol and size
are applied to the interior, not to the line. But it works with 2
separate styles.

Subject: [UMN_MAPSERVER-USERS] Dashed Outline

I want the outline of a polygon (esri world base country layer) to be
dashed, but couldn't find anything about how to achieve this.  No
documentation, no mapfile snippets.  Is it possible at all to have
dashed outlines?

A hack, that seems to work is
 * duplicate the layer in the mapfile
 * say TYPE POLYGON to the one
 * and TYPE LINE to the other
 * the first defines the filling
 * the latter the outline

Cheers,
