TdxMapControlCustomProjection Class

The base class for classes that implement map projections.

Declaration

TdxMapControlCustomProjection = class(
    TcxInterfacedPersistent
)

Remarks

This class provides geographic conversion functions that are common to all map projections. TdxMapControlCustomProjection descendants primarily override these functions to implement the projection-specific functionality. Call the dxRegisteredMapProjections global function to access map projection classes that are registered for use with map layers.
