Constructor Detail

AimsPath

public AimsPath()

Creates a path point object with no arguments.

AimsPath

public AimsPath(AimsPoints pts)

Creates a new path object with an AimsPoints object.

Parameters:

pts - The points.

Method Detail

getLength

public double getLength()

Gets the length of the path.

Returns:

The length of the path.

getClosestVertex

public AimsPoint getClosestVertex(AimsPoint pt)

Gets the closest vertex in the AimsPath to the specified point.

Parameters:

pt - The point to compare the vertexes to.

Returns:

The closest vertex to the specified point, or null if there are no points in the path.

addPoint

public void addPoint(AimsPoint pt)

Adds a point to the path.

Parameters:

pt - The point to add to the path.

getPoints

public AimsPoints getPoints()

Gets the points of the path object.

densify

public void densify(double distance)

Densifies the points in the shape by a distance.

Parameters:

distance - The densify distance.

generalize

public void generalize(double distance)

Generalizes the points in the shape by a distance.

Parameters:

distance - The generalize distance.

offsetBy

public void offsetBy(AimsPoint offset)

Offsets the points in the path by the x and y in a point.

Parameters:

offset - An AimsPoint object containing the offset.

setPoints

public void setPoints(AimsPoints points)

Sets the points of the path object.

Parameters:

points - An AimsPoints object containing the path points.

getExtent

public AimsEnvelope getExtent()

Returns the extent of the path, or null if the path has no points.

Returns:

An AimsEnvelope containing the extent.

toString

public java.lang.String toString()

Returns a text representation of of this object.

Returns:

A string describing the object

toAxlString

public java.lang.String toAxlString()

Parameters:

projection - The original projection system.

Returns:

An object containing the projected coordinates.

unproject

public AimsPath unproject(Projection projection)

Unprojects this object to geographic from the specified projection.

Parameters:

projection - The projection system.

Returns:
