[Mapserver-users] scalebar params.

MapServer version 4.0.1 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ
SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT INPUT=EPPL7 INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE

No errors in the javascript console. Its been many years since I did any serious
js coding but as far as I can tell there is nothing wrong with the code itself.

Im using Mozilla 1.6a for my main browser. I tried clearing the cache to see if
it was related to that with no success either. Went so far as to manually remove
the cache files.

One thing to note is that in the demo even using my current data the scalebar
displays properly and updates accordingly.

Is there by chance a way that I can tell it in this js code to dump this file
right to my tmp dir that mapserver normally uses?

Jason.
