Hello Mapguides List,
I am developing an aplication about vehicle tracking and i have beed
reading the MgOpenSourceDevGuide.pdf.
I need to draw the car image about location on the map but i don´t
understand how to do it.
Coul you help me with this please.
My code is the follow:
html
body onLoad=OnPageLoad()
?php
function add_layer_definition_to_map($layerDefinition, $layerName,
$layerLegendLabel, $sessionId, $resourceService, $map)
// Adds the layer definition (XML) to the map.
// Returns the layer.
{
echo Iniciando metodo add_layer_definition_to_map...;
global $schemaDirectory;
// Validate the XML.
$domDocument = new DOMDocument;
$domDocument-loadXML($layerDefinition);
// Save the new layer definition to the session repository
$byteSource = new MgByteSource($layerDefinition,
strlen($layerDefinition));
echo br/ echo 111 br/;
$byteSource-SetMimeType(MgMimeType::Xml);
echo br/ echo br/;
echo session: .$sessionId;
$resourceID = new
MgResourceIdentifier(Session:$sessionId//$layerName.LayerDefinition);
echo br/ echo br/;
$resourceService-SetResource($resourceID, $byteSource-GetReader(),
null);
echo br/ echo br/;
$newLayer = add_layer_resource_to_map($resourceID, $resourceService,
$layerName, $layerLegendLabel, $map);
echo br/ echo br/;
return $newLayer;
}
function add_layer_resource_to_map($layerResourceID, $resourceService,
$layerName, $layerLegendLabel, $map)
// Adds a layer defition (which can be stored either in the Library or a
session
// repository) to the map.
// Returns the layer.
{
$newLayer = new MgLayer($layerResourceID, $resourceService);
// Add the new layer to the map's layer collection
$newLayer-SetName($layerName);
$newLayer-SetVisible(true);
$newLayer-SetLegendLabel($layerLegendLabel);
$newLayer-SetDisplayInLegend(true);
$newLayer-SetDisplayInLegend(true);
$layerCollection = $map-GetLayers();
if (! $layerCollection-Contains($layerName) )
{
// Insert the new layer at position 0 so it is at the top
// of the drawing order
$layerCollection-Insert(0, $newLayer);
}
return $newLayer;
}
