[mapserver-users] Dynamic Change

[Steve Lime]

There's a template substitution that computes the exact center of the
image (in pixels for you) based on the just created image dimensions.
Try using:

  <input type="hidden" name="imgxy" value="[center]">

Hi all.

I change de "mapsize" with this

      <SELECT SIZE="1" NAME="mapsize">
         <OPTION VALUE="[mapsize]"> [mapsize]
         <OPTION VALUE="800 800">800 x 800
         <OPTION VALUE="600 600">600 x 600
         <OPTION VALUE="500 500">500 x 500
         <OPTION VALUE="400 400">400 x 400
         <OPTION VALUE="300 300">300 x 300
         <OPTION VALUE="200 200">200 x 200
      </SELECT><br>

and this change requires the update of the value of  "X and Y"
dynamically

       <input type="hidden" name="imgxy" value="X Y">  .

Without this the map loses its centralization.

Can some one help me ?

Thanks.
