MgPoint Class Reference
[MgPoint]
Inherits MgGeometry.
Detailed Description
An MgPoint is a 0-dimensional geometry and represents a single location in coordinate space.
- Remarks:
- An instance of this class is constructed by calling a non-static MgGeometryFactory::CreatePoint() method and, once constructed, is immutable.
Example (PHP)
The following code shows the construction of a point
The following code shows the construction of a point
$geometryFactory = new MgGeometryFactory(); // create a coordinate $oordinate = $geometryFactory->CreateCoordinateXY(0,2); // create a point $point = $geometryFactory->CreatePoint($coordinate); // print out the Agf Text string for the geometry $pointAgfText = $wktReaderWriter->Write($point); echo "AGF Text representation of Point: $pointAgfText\n";
Example (C#)
using OSGeo.MapGuide; private MgPoint pt11; private MgPoint pt11FromText; private String pt11TextSpec = "POINT XY ( 1 1 )"; private MgWktReaderWriter wktReaderWriter; private MgGeometryFactory geometryFactory; private String geometryAgfText; public MgPoint CreateAPointXY(double x, double y) { MgCoordinate coord = geometryFactory.CreateCoordinateXY(x, y); return geometryFactory.CreatePoint(coord); } wktReaderWriter = new MgWktReaderWriter(); geometryFactory = new MgGeometryFactory(); // create a geometry using the geometry factory pt11 = CreateAPointXY(1, 1); // create a geometry from an Agf textual specification pt11FromText = wktReaderWriter.Read(pt11TextSpec) as MgPoint; // print out the Agf Text string for the geometry geometryAgfText = wktReaderWriter.Write(pt11); // geometryAgfText now contains: // "POINT XY ( 1 1 )"
