Member Function Documentation

◆ GetPoint()

Luciad.Cartesian.Coordinate Luciad.Geometries.Polyline.GetPoint ( uint index )

inline

Returns the coordinate for the requested index.

Parameters

index the index of the requested point.

Returns: the point at the index.

Exceptions

System.ArgumentException when requesting an invalid index.

◆ InsertPoint()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.InsertPoint	(	uint	index,
		Luciad.Cartesian.Coordinate	newLocation
	)

inline

Creates a new Polyline with an newly inserted control point.

Parameters

index	the index of the newly inserted control point. Should be in `[0, {@link Luciad.Geometries.Polyline#PointCount getPointCount()}]`. For index 0, a new point will be added at the start of the `Polyline`. For index `getPointCount()`, a new point will be added at the end of the `Polyline`. For other index values, a point will be added between 2 other points.
newLocation	the location of the new point

Returns: a new geometry

Exceptions

System.ArgumentException for an invalid index

Since: 2020.1

◆ MovePoint()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.MovePoint	(	uint	index,
		Luciad.Cartesian.Coordinate	newLocation
	)

inline

Creates a new Polyline with a moved control point.

Parameters

index	the index of the point to move. Should be in `[0, {@link Luciad.Geometries.Polyline#PointCount getPointCount()} - 1]`.
newLocation	the new location of the point

Returns: a new geometry

Exceptions

System.ArgumentException for an invalid index

Since: 2020.1

◆ RemovePoint()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.RemovePoint ( uint index )

inline

Creates a new Polyline with a control point removed.

This methods returns a copy of the polyline if its point count is less or equal to 2.

Parameters

index the index of the point to be removed. Should be in [0, {@link Luciad.Geometries.Polyline#PointCount getPointCount()} - 1].

Returns: a new geometry

Exceptions

System.ArgumentException for an invalid index

Since: 2020.1

◆ Translate()

Luciad.Geometries.Polyline Luciad.Geometries.Polyline.Translate ( Luciad.Cartesian.Coordinate translation )

inline

Translates the entire polyline.

Note: when the polyline is defined in a geodetic reference and uses geodetic interpolation, the translation is not performed by translating the points one by one. Instead, a translation method is used that better preserves the shape of the polyline when moving it towards (or away from) the poles.

Parameters

translation the translation vector

Returns: a new, translated geometry

Since: 2020.1
