[Mapserver-users] Pixel....

[Debbie Pagurek]

you need to have an empty point layer set up in your mapfile that defines the colors to use, and then you can add the appropriate name value pairs in the URL.  See Steve Lime's post for more information:

Steve,
How I make to make this passing for parameters in the URL for the MapServer? 
  I have the following situation, the center of the map is latitude -23 and longitude -46 and that to insert a point in latitude -23,55 and longitude -46.46 the imgext=-47 -24 -45 -22. 

How I can insert this point?

Thanks

João Paulo
