[Mapserver-users] automatically resize

[Eric Bridger]

You can use SYMBOLSCALE in a LAYER in your map file which works with
both CLASS MINSIZE, MAXSIZE and LABEL MINSIZE MAXSIZE to scale both the
symbol and text.  You'll need to use truetype fonts and play around with
the SYMBOLSCALE value which changes with the zoom-in/out.  

Here's an example:
LAYER
  NAME "cities"
  TYPE POINT
  DATA "/mapserver/data/vector/tiger/cities"
  STATUS DEFAULT
  LABELITEM "PLACE"
  SYMBOLSCALE 1320000
  CLASS
    NAME "City"
    SYMBOL "circle"
    COLOR  255 255 0
    OUTLINECOLOR  0 0 0
    SIZE  8
    LABEL
      TYPE TRUETYPE
      FONT helr
      SIZE 9
      COLOR 0 0 0
      ANTIALIAS TRUE
      POSITION AUTO
      PARTIALS FALSE
      MAXSIZE 13
      MINSIZE 8
    END
  END
END
