<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>For some reason mapguide is unable to understand the
geometry of my shapefile. The shapefile is a polygon with the geometry
information contained in the ‘Shape’ field. However when I use the ‘Shape’
field in the following code I get an error which states: “The specified
object was not found – GetItem line 115”. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Here is the code:</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>
$byteReader = $featureReader->GetGeometry('Shape');</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>
$geometry = $geometryReaderWriter->Read($byteReader);</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>
$point = $geometry->GetCentroid();</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>
$x = $point->GetCoordinate()->GetX();</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>
$y = $point->GetCoordinate()->GetY();</span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>so what I think should happen here is the GetGeometry
function should look at the ‘Shape’ field, identify that the shapefile
is a polygon, then get the xy coordinates of the centroid of the polygon which
is then sent to another function which can then zoom to those coordinates.
But I keep getting the error that I mentioned. Could anyone point me in the
right direction?</span></font></p>
