Dear Oliver Christen,
Using Mapserver 5.6.0 and AGG rendering, you can achieve what
you want by using a combination of ellipse size and gap size
in the symbol definition.
There is something strange in the calculations (a gap of
about half the ellipse size seems to produce touching symbols),
so in your case, you could try to use 8 as the diameter of the
ellipses, and 20 + 4 (half the ellipse size) = 24 as the
gap:
symbol
name dots
type ellipse
points 8 8 end
gap 24
end

thank you Thomas
so if I have a dot of, for example, 8px and I want a space pf 20px
between the dots, I need a gap of 20/8 = 2.5
but as far as I can see, Mapserver doesnt like none-integer value for gap.
what should I do? :(

gap in pixels = symbol->gap * style->size

GAP 20 is really giving unwanted result:

<http://dev.camptocamp.com/%7Eochriste/tilecache9.png>
though using only one style instead of two seems to solve the
oval problem (but why ???)
style
symbol "dots"
size 8
color 204 102 0
outlinecolor 102 51 0
end
I dont understand how GAP is supposed working:
with GAP 2, I had ~10px between dots,
with GAP 3, I had ~18px between dots,
with GAP 4, I had ~26px between dots
whats the logic ?

Hi Thomas :)
thanks for the answer, but sadely it didnt solve my problem:
here are a few tests I did:
using GAP 20 gave me really weird result:
http://dev.camptocamp.com/~ochriste/tilecache6_gap_20.png
<http://dev.camptocamp.com/%7Eochriste/tilecache6_gap_20.png>
using PATTERN 1 22 END gave me better result, but the
dot are still slightly oval:
http://dev.camptocamp.com/~ochriste/tilecache7_pattern.png
<http://dev.camptocamp.com/%7Eochriste/tilecache7_pattern.png>
I wondered if the visual effect may have come from the
fact im pilling up two circle one over the other, but
even when trying to display only the outer or inner
circles, the circle are still slightly off:
http://dev.camptocamp.com/~ochriste/tilecache4_outercircle.png
<http://dev.camptocamp.com/%7Eochriste/tilecache4_outercircle.png>
http://dev.camptocamp.com/~ochriste/tilecache5_innercircle.png
<http://dev.camptocamp.com/%7Eochriste/tilecache5_innercircle.png>
(both at once
http://dev.camptocamp.com/~ochriste/tilecache3_bothcircle.png
<http://dev.camptocamp.com/%7Eochriste/tilecache3_bothcircle.png>)
any other idea? ^_^

hi Oliver :)
try with GAP 20 instead of STYLE 1 20 END (which is
deprecated btw, use PATTERN now)
cheers,

hello
I have a weird problem with symbology.
Im rendering a line with dots, but the dots are
not round but slightly oval, see image
http://dev.camptocamp.com/~ochriste/tilecache.png
<http://dev.camptocamp.com/%7Eochriste/tilecache.png>
Any idea what could be the cause ?
Here is my symbol definition:
SYMBOL
NAME "linie-gepunkt10"
TYPE ELLIPSE
POINTS
1 1
END
STYLE
1 20
END
FILLED TRUE
END
and my layer's class definition:
CLASS
EXPRESSION "3"
MAXSCALEDENOM 200001
STYLE
SYMBOL "linie-gepunkt10"
SIZE 10
COLOR 102 51 0
END
STYLE
SYMBOL "linie-gepunkt10"
SIZE 8
COLOR 204 102 0
END
END
and the map outputformat:
OUTPUTFORMAT
NAME png
DRIVER "AGG/PNG"
MIMETYPE "image/png"
IMAGEMODE RGBA
EXTENSION "png"
FORMATOPTION "INTERLACE=OFF"
END
