Members Summary

Public Constructors

UnmanagedProj4Projection()

  • This is the default constructor for this class.
Remarks
  • This conctructor pass nothing. After this cconstructor , you should set the InternalProjectionParametersString property and ExternalProjectionParametersString property before open to use.
Parameters

UnmanagedProj4Projection(String,String)

  • This is a constructor for the class.
Remarks
  • This constructor allows you to pass in Proj4 text parameters for the to and from projection. The parameters typically look like “+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs” You should use this constructor when you know the parameters. If you know the SRID directly you can use the other constructor that takes the SRID.
Parameters
  • internalProjectionParametersString
    • Type:String
    • Description:This parameter is the projection parameters describing the data.
  • externalProjectionParametersString
    • Type:String
    • Description:This parameter is the projection parameters describing the projection you want to go to.

UnmanagedProj4Projection(Int32,Int32)

  • This is a constructor for the class.
Remarks
  • This constructor allows you to pass in Proj4 srid parameters for the to and from projection. The parameters typically look like 4320 stands for “+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs” and 4604 stands for “ +proj=longlat +ellps=clrk80 +towgs84=174,359,365,0,0,0,0 +no_defs”. You should use this constructor when you know the parameters. If you know the SRID directly you can use the other constructor that takes the SRID.
Parameters
  • internalEpsgSrid
    • Type:Int32
    • Description:This parameter is the projection srid parameter describing the data.
  • externalEpsgSrid
    • Type:Int32
    • Description:This parameter is the projection srid parameter describing the projection you want to go to.

Public Methods

Dispose()

  • N/A
Remarks
  • This dispose releases the handles of the Proj4 library. You should normally use Close instead of dispose unless you really want to never use this instance again. Normally when a layer is finished drawing it will call the Close of the projection class. This allows the object to be serialize but used again in the future. You should only use the Dispose method when you do not want to use this class again.

Protected Methods

OpenCore()

  • N/A
Remarks
  • As this is the core version of the Open method it is intended to be overridden in inherited version of the class. When overriding you will be responsible for getting the projection classes state ready for doing projections. In this override we call the Proj4 methods get it ready for projection.
Return Value
  • Type:Void
  • Description:None
Parameters

CloseCore()

  • N/A
Remarks
  • As this is the core version of the Close method it is intended to be overridden in inherited version of the class. When overriding you will be responsible freeing any state you have maintained and getting the class ready to serialization if necessary. Note that the object may be opened again so you want to make sure you can open and close the object multiple tiles without any ill effects. In this override we call the Proj4 methods get release the handles and memory.
Return Value
  • Type:Void
  • Description:None
Parameters

ConvertToExternalProjectionCore(Double[],Double[])

  • N/A
Remarks
  • This method returns a projected vertex based on the coordinates passed in. You will need to override this method for the Projection class. Typically you can call the projection utility library that has interfaces for dozens of different types of projections.
Return Value
  • Type:Vertex[]
  • Description:This method returns a projected vertices based on the coordinates passed in.
Parameters
  • x
    • Type:Double[]
    • Description:This parameter is the X values of the points that will be projected.
  • y
    • Type:Double[]
    • Description:This parameter is the Y values of the points that will be projected.

ConvertToInternalProjectionCore(Double[],Double[])

  • N/A
Remarks
  • This method returns a de-projected vertex based on the coordinates passed in. You will need to override this method for the Projection class. Typically you can call the projection utility library that has interfaces for dozens of different types of projections. The de-projection is important because inside of the FeatureSource you will in many cases to to and from various projections.
Return Value
  • Type:Vertex[]
  • Description:This method returns a de-projected vertices based on the coordinates passed in.
Parameters
  • x
    • Type:Double[]
    • Description:This parameter is the X values of the points that will be de-projected.
  • y
    • Type:Double[]
    • Description:This parameter is the Y values of the points that will be de-projected.
