scale?

Mon Jan 30 09:14:15 PST 2006

It should be substituted. Try with some other simple values like [extent] or [mapx] &nbsp [mapy] on your template and their values should be displayed. You can also try using mode=browse into your url that calls mapserv. www.host.com/cgi-bin/mapserv?mode=browse&map=yourmapfile.map.......

  Muy Bien!
  Thanks for that Luis.

  You say that the subsitution is done by mapserver CGI? I've insterted the following code into my html template as per a previous suggestion:

  <td>

  Map Scale: &nbsp &nbsp &nbsp 1:[scale]

  </td>

  However the output of this code doesnt is as follows:

  Map Scale:    1:[scale]

  It would seem that the scale value isnt being subsituted. Can you suggest what might (or might not) be causing this?

    Gracias

    Jeremy

    Jeremy:

    The substitution of the [scale] value is done by mapserver CGI.
    this is the javascript function:
    function TomaEscala(scale){

    var escala, escalaStr, decimal;

    escala = scale; 

    escala *= 100; 

    escala = Math.round(escala); 

    escala /= 100; 

    escalaStr = Math.abs(escala).toString(); 

    entero = escalaStr.substr (0,escalaStr.length-3);

    if (entero.length > 3) {

        longitud = entero.length % 3;

        while (longitud < entero.length) {

        if (longitud == 0) {

            longitud = 3;

        }

        entero = entero.substr (0,longitud) + "," + entero.substr(longitud,entero.length);

        longitud += 4;

        }

     }

      escalaStr = entero;

       if (document.createTextNode){

       var mytext=document.createTextNode(escalaStr)

       document.getElementById("MyElementID").appendChild(mytext)

       }

    }

    You can call this fuction on the <body onload="TomaEscala([scale]);"> of your template.

    (some words are in spanish but I'm sure is not a problem)

    Regards,

    Luis

      Thanks for the reply Luis,
      I would indeed like to see your code. 

      >>you can use [scale] in your template file.

      Formating aside, Im assuming that the template file need to have some extra code inorder to subsitute [scale] with the value of the scale. Is this assumption correct? If so, where can I find that code?

      Thanks
      Jeremy

        Jeremy:

        you can use [scale] in your template file.

        Use some javascript to format the value of scale (like: 1:50,000 or 1:50.000). I have a small code that does this formating using a getElementById. if you want it I can mail it to you.

        Regards
        Luis

          Hi All,
          This should be an easy question, however I cant find information on it....

          How does one display the scale of a map? Im looking to have mapserver (or other means?) produce a scale like "1:50 000", rather than the scale bar. 

          Thanks
          Jeremy

            Subject: [UMN_MAPSERVER-USERS] setting variable value in mapfile

            Hello,

            I know I can easily use variables in a mapfile, when the value comes from cookies or a GET request.  But what about setting a variable inside the mapfile itself?
            Something like:

            HIGHWAY_MAX_SCALE=2000000 
            HIGHWAY_MIN_SCALE=90000

            or

            HIGHWAY_COLOR="255 250 115"

            then be able to use something like:

            COLOR  %HIGHWAY_COLOR% 

            in a CLASS

            That way if I decide I want to change a color, I can change it once, and have it take affect for everywhere else? 

            Thanks,

            Jerl
