[Mapserver-users] ms_newprojectionObj - change from v3.6 to v4.0??

[Paul Spencer]

Debbie, from the php mapscript class reference, it looks like it returns 
a result code instead of a new rectobj, and the projection is applied to 
the actual rectobj rather than a copy.  So your code should read:

$newproj=ms_newprojectionObj( "proj=robin,lon_0=0,x_0=0,y_0=0" );
$latlon = ms_newprojectionObj (
                 "proj=longlat,ellps=GRS80,datum=NAD83,no_defs" );

$oRect= ms_newRectObj();
$oRect->setextent( $bounds[0], $bounds[1],
                    $bounds[2], $bounds[3] );
$oRect->project( $latlon,$newproj);  //the extent in
$map->setextent( $oRect->minx, $oRect->miny,
                  $oRect->maxx, $oRect->maxy );

Cheers,

Paul
