Thanks Joe,
Yeah, I eventually figured that out. I tried to use a circle gradient,
but the circle overlaps at the start/end of the polygon making it darker
there. You also have to render the polygon first as as a LINE to get the
brush applied then again as a polygon to get the fill. You might be able
to do it in one step, but I have not been able to get that to work.
I'm still playing with this to get the effect I want.

Can you use an image as a line brush, where the image is a gradient from
a dark point at the center to a light, nearly transparent shade?

Hi all,
I want to render and island polygon with a big fat outline color in
a dark blue the fades in distance from the island. I'm using AGG and
I tried this:
LAYER
NAME "Islands"
STATUS DEFAULT
DATA "coast"
TYPE POLYGON
LABELITEM "ISLAND"
LABELCACHE OFF
CLASS
STYLE
SYMBOL "circle"
OUTLINECOLOR 0 192 243
SIZE 20
END
STYLE
COLOR 242 239 233
END
END
END
Which sort of works but there is very little fade.
If I use:
STYLE
OUTLINECOLOR 0 192 243
WIDTH 20
END
I get horrible artifacts all along the outline. Is there a way to
control the amount of fade in the outline. Can I make a transparent
ball that fades with radius to achieve this?
Thanks,
-Steve
