Title

FM12 GetMap Zoom Control

Post

     I am using the Custom Function GetMap with the following modifications:

     Let     (
         [
         address =     Substitute     (
                                 address1 & " " &
                                 city & " " &
                                 state & " " &
                                 postalCode & " " &
                                 country ;
                                 " " ; "+"
                                 ) ;
         size =         GetLayoutObjectAttribute ( webViewerName ; "width" ) & "x" & GetLayoutObjectAttribute ( webViewerName ; "height" )
         ] ;

         "http://maps.google.com/maps/api/staticmap?center="
                 & address &
                     "&zoom=" & zoom &
                         "&markers="
                             & address &
                                 "&size="
                                     & size &
                                         "&sensor=false"
         )

     What I am trying to accomplish is to add a "Zoom In / Zoom Out" function to this like the  "+" and "-" buttons on the standard Google map display.  What do I have to do to achieve this?

     My "Custom Web Address" in my Web Viewer Setup that I'm using is:

     GetMap ( "Map" ; 14 ; Phone Book::Residence Street Address ;Phone Book::City ; Phone Book::Province ; Phone Book::Postal Code ; Phone Book::Country )

     This works exactly like I want it to except for the lack of a zoom control.
