QueryByRect Problems on shp point

[Francesco Sozzi]

Hi Lowell,

no, I think coordinates are correct.
I create rectangle by:

$newExtentScreenCoordStr = explode(" ",$hiddenMapImageBox);
$newExtentScreenCoord = ms_newrectObj();
$newExtentScreenCoord->setextent($newExtentScreenCoordStr[0],
   $newExtentScreenCoordStr[1],
   $newExtentScreenCoordStr[2],
   $newExtentScreenCoordStr[3]);

Where $hiddenMapImageBox is a box created by jBox.

Please also note that the same rectangle works properly for lines and
polygons and that it works properly for point on Oracle.

Best regards

Francesco
