Hi,
I can't see any mistakes.
I tried to test this on with 6.4.2 and 7.0.1 (sorry I have not
installed 7.0.2 yet), and am not able to reproduce the behaviour
that you describe. ANCHORPOINT seems to work as expected.
Which Mapserver version are you using?
I have run it using shp2img -m
I attach the resulting images (the last number in the file name
reflects the symbolscaledenominator that has been used).
Here is my complete mapfile:
MAP

EXTENT 0 0 100 100

NAME "arrowv"
TYPE vector
ANCHORPOINT 0.5 1

END
END
SYMBOL

FILLED TRUE

It seems like my symbol's ANCHORPOINT is not being scaled when my style
definition uses MINSIZE, MAXSIZE and MAXSCALEDENOM.
Here's my symbol definition:
SYMBOL
NAME "arrowv"
TYPE vector
ANCHORPOINT 0.5 1
POINTS
0 2
1 0
2 2
-99 -99
1 0
1 3
END
END
and my style definition:
STYLE
SYMBOL "arrowv"
SIZE 40
COLOR 0 0 255
ANGLE [angle]
END
Which produces what I want:
(The red dot is the map x, y insertion point)
but when I add SYMBOLSCALEDENOM and change my symbol definition to:
STYLE
SYMBOL "arrowv"
MINSIZE 15
MAXSIZE 40
COLOR 0 0 255
MINWIDTH 1
MAXWIDTH 1
ANGLE [angle]
END
I get:
The ANCHORPOINT is not scaled along with the symbol. A little hard to
see in these two, but the ANCHORPOINT is being used, just not scaled:
ANCHORPOINT 0 0
ANCHORPOINT 1 1
Am I doing something wrong?
Thanks,
Rich
