FW: [ka-Map-users] Drawing routes in ka-map

Tue Oct 4 09:16:49 EDT 2005

Hello Jeremy,

Look at the code below, in the variable s I have a WKT polygon definition.
The coordinates are in the same system like the map file.
You have to add the following  to your html file at the appropriate
positions.
  <html xmlns:vml="urn:schemas-microsoft-com:vml">

  <OBJECT id="VMLRender"
classid="CLSID:10072CEC-8CC1-11D1-986E-00A0C955B42E" 
  </OBJECT>

  <style>
	vml\:* { behavior: url(#VMLRender) }
  </style>

The problem is I can't get rid of them when I want to remove the drawing
canvas.
Hope this helps, excuse my english

Best regards,
Jochen

So has anyone sucessfully done this? How did you tie your VML drawing to the
kaMap object?  I tried drawing it in a DIV embedded in a marker anchored to
the coordinate system origin (0,0), but that does not seem to work. Any
ideas?
