FGF Text
 
 
 

FGF Text is the textual analogue to the binary FGF format. It is a superset of the OGC WKT format. XY dimensionality is the default, and is optional. FGF Text can be used to represent any geometry value in the Geometry API, whether or not it originates from the FGF geometry factory. Conversions are done with the following methods:

  • FdoGeometryFactoryAbstract:: CreateGeometry(FdoString* text);
  • FdoIGeometry:: GetText();”

A BNF for the FGF textual specification is contained in the topic Geometry Value.
