[Chameleon] add url to legend icon in legend template file

[He, Matt Yubin]

Hi list:

 

            In legend_template.html file, there is a line of code for
display legend icon:    

<td><img src="[leg_icon width=20 height=18]" width="20"
height="20"></td>

 

 

      In my map file, I defined my legend image as this:

class

   keyimage "/legend_images/mylegend.jpg"

end

 

      I am trying to add a URL to the legend icon in
legend_template.html file, so that when user click the legend icon, it
shows the real image defined in "KEYIMAGE", e.g.:

<td><a href="[XXXXX]"><img src="[leg_icon width=20 height=18]"
width="20" height="20"></a></td>

 

Does anyone know what I should put in (to replace XXXXX) to refer to the
keyimage?

 

 

Thanks.

 

 

Matt
