[Mapserver-users] changing scalebar on the fly

[Tom.Kralidis at CCRS.NRCan.gc.ca]

Hi,

Using MapServer CGI 3.5, my mapfile defines a scalebar as follows:

 SCALEBAR
  STATUS       ON
  INTERVALS    4
  SIZE         200 2
  STYLE        1
  COLOR        255 255 255
  OUTLINECOLOR 0 0 0
  UNITS        KILOMETERS
  TRANSPARENT  ON
  LABEL
   COLOR 255 255 255
   SIZE  SMALL
  END
 END

...for maps viewed in lat/long.  My mapfile is geared towards a lat/long (or
EPSG 4326) application, and object defs are defined as such.

However, my when my app changes to LCC, I'd like the units of my scalebar to
be meters to accomodate this.

I tried passing this to the CGI with 'map_scalebar_units=meters', which
seems to have been recognized (units sign in output scalebar is 'm'), but it
appears as if all the text and interval drawings become drawn atop
eachother.  Here's an example snapshot:

Any ideas as to what's going on here?

Thanks alot

..Tom
