<!– Class –> This projection class uses the Proj4 engine to project data from one Srid to another.

This projection class uses the Proj4 engine to project data from one Srid to another. Proj4 is a very popular projection library the support thousands for projections. It uses a special text format to feed in parameters about the to and from projection. Though it uses its own format many organizations have recognized it and provide their projection definition in this format. Within this class we support the latest EPSG (European Petroleum Survey Group) SRID (Spatial Reference System Identifiers) list. You can find more information about these on the web. The SRID list is very popular and we include a text version with in our install.

Note that one thing that confuses people is that when they go to or from latitude and longitude they do not know what SRID to use. The proper SRID is 4326 for WGS84 pair coordinates in degrees with Greenwich as the central meridian.

This is the default constructor for this class.

This conctructor pass nothing. After this cconstructor , you should set the InternalProjectionParametersString property and ExternalProjectionParametersString property before open to use.

This is a constructor for the class.

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”

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.

Create a copy of Projection using the deep clone process.

The difference between deep clone and shallow clone is as follows: In shallow cloning, only the object is copied; the objects within it are not. By contrast, deep cloning copies the cloned object as well as all the objects within.

As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

This method closes the projection and gets it ready to serialization if necessary.

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.

This property specifies the Boundary for decimaldegree values.

The default boundary is(-179.9, 89.9, 179.9, -89.9). That means when I want to project a PointShape(-179,91,89.91) out, in fact what it projects is (-179.9,89.9) because of its out of boundary.

This property gets the state of the projection (whether it is opened or closed).

This method will reflect whether the projection is opened or closed. It is set in the concrete methods Open and Close, so if you inherit from this class and override OpenCore or CloseCore, you will not need to be concerned with setting this property.
