MgWktReaderWriter Class Reference
[MgWktReaderWriter]

Inherits MgDisposable.

List of all members.

Detailed Description

Translates a string in AGF (Autodesk Geometry Format) Text format into an MgGeometry object and vice versa. See the AGF Text topic. .

Example (PHP) 
 $wktReaderWriter = new MgWktReaderWriter();
 $agfReaderWriter = new MgAgfReaderWriter();
 // In the string to geometry direction:
 $agfTextPoint = "POINT XY (0 0)";
 $pointGeometryFromWkt = $wktReaderWriter->Read($agfTextPoint);
 $byteReader = $agfReaderWriter->Write($pointGeometryFromAgfText);
 // In the geometry to string direction:
 $pointGeometryFromBytes = $agfReaderWriter->Read($byteReader);
 $agfTextPoint = $wktReaderWriter->Write($pointGeometryFromBytes);
 // prints "POINT XY (0 0)" to screen
 echo "$agfTextPoint\n";

Example (C#) 
 private MgAgfReaderWriter agfReaderWriter;
 private MgWktReaderWriter wktReaderWriter;
 private MgPoint pt11FromText;
 private MgPoint pt11;
 private String pt11TextSpec = "POINT XY ( 1 1 )";
 private MgByteReader byteReader;
 private String geometryAgfText;

 agfReaderWriter = new MgAgfReaderWriter();
 wktReaderWriter = new MgWktReaderWriter();
 // In the string to geometry direction:
 pt11FromText = wktReaderWriter.Read(pt11TextSpec) as MgPoint;
 byteReader = agfReaderWriter.Write(pt11FromText);
 // In the geometry to string direction:
 pt11 = agfReaderWriter.Read(byteReader);
 geometryAgfText = wktReaderWriter.Write(pt11);
 // geometryAgfText now contains the text representation of the geometry
