PointTransformer – Global Mapper

Inherits from

System.Object

Description

The PointTransformer is a utility class with the primary function of converting coordinate points from a source reference system to a target reference system. It can only be created from a valid ConcatenatedCoordtransform, and is only usable for a single instance of the parent object. It extends methods for creating valid CoordPoints for the transformation, as well as informative methods for describing the steps used in the transformation process. For more detailed information on using this class, please refer to lesson 7 and 8 in the getting started guide.

Constructors

Constructor	Description
PointTransformer	Creates a new instance of the PointTransformer class.

Properties

Property	Description
ConcatenatedTransformOwner	Gets the ConcatenatedTransform that was used to generate this PointTransformer

Methods

Method	Description
ConvertSourceBaseToTarget	Convert a point in the geodetic base of the source to a point in the geodetic base of the target. Values are assumed to be in degrees.
ConvertSourceToTarget	Convert a source coord point to a target coord point, using the transforms from the concatenated transform that generated this.
ConvertTargetBaseToSource	Convert a point in the geodetic base of the target to a point in the geodetic base of the source. Values are assumed to be in degrees.
ConvertTargetToSource	Convert a target coord point to a source coord point, using the transforms from the concatenated transform that generated this.
GetDescription	Gets a user's description of this transformer.
GetOperations	Return a cloned copy of the Operations use in this PointTransformer.
GetOperationsEx	Returns a List of CoordTransformInfos of all the transform operations used in this PointTransformer. This version also takes into account transforms that might be part of any EarlyBoundCoordSys contained in the CCT.
GetSourceCoordPoint	Return a cloned copy of the appropriate source point style for use in this PointTransformer.
GetTargetCoordPoint	Return a cloned copy of the appropriate target point style for use in this PointTransformer.
GetTransformDescription	Gets a user's description of this transformer's transform piece.
Inherited Method	Description
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object).
GetHashCode	Serves as the default hash function. (Inherited from Object).
GetType	Gets the Type of the current instance. (Inherited from Object).
ToString	Returns a string that represents the current object. (Inherited from Object).
