[mapserver-users] confused on styling polygon

[Havard Tveite]

According to the STYLE-> WIDTH documentation, for POLYGON
symbols (filled symbols of type vector) WIDTH refers to
the width of the outline of the symbol:

"If used with SYMBOL and OUTLINECOLOR, WIDTH specifies the width of the 
symbol outlines. This applies to SYMBOL TYPE vector (polygons), ellipse 
and truetype."

The documentation is probably a bit imprecise in not
including the word "filled" for the vector and ellipse types.

If you add OUTLINECOLOR 255 0 0, you will see the outline
of the symbol in red with a width of 5.

Apparently, leaving out OUTLINECOLOR seems to be equivalent
to OUTLINECOLOR 255 255 255, and since your outline is
thicker than the half the width of the symbol, the outline
will erase the blue (0 0 252) interior of the symbol.

If you want to see some of the interior of the symbol
(blue), you will have to reduce the value of WIDTH or
increase the value of SIZE.
