[Chameleon] How to pass forward user specific extents?

[William A. Bronsema]

Hi Ken,

All you need to do is determine the extent you wish to use and set it 
between the CWCInitialize call and the CWCExecute call.

Your code would look something like this:

// init app
$oApp->CWCInitialize( $szTemplateName, $szMapFile  );

// determine if is first load or not
......

// get user extents
......

// override extent if necessary
if ( $bIsFirstLoad )
{
     // set extent
     $oApp->moMapSession->oMap->setextent(
                                      $dUserMinX,
                                      $dUserMinY,
                                      $dUserMaxX,
                                      $dUserMaxY );
}

// execute app
$oApp->CWCExecute();


Hope this helps.

Regards,
Bill
