Class Densifier

java.lang.Object
org.locationtech.jts.densify.Densifier
public class Densifier extends Object
Densifies a Geometry by inserting extra vertices along the line segments contained in the geometry. All segments in the created densified geometry will be no longer than the given distance tolerance (that is, all segments in the output will have length less than or equal to the distance tolerance). The coordinates created during densification respect the input geometry's PrecisionModel.

By default polygonal results are processed to ensure they are valid. This processing is costly, and it is very rare for results to be invalid. Validation processing can be disabled by calling the setValidate(boolean) method.

Note: At some future point this class will offer a variety of densification strategies.

  • Constructor Details

    • Densifier

      public Densifier(Geometry inputGeom)
      Creates a new densifier instance.
      Parameters:
      inputGeom -

  • Method Details

    • densify

      public static Geometry densify(Geometry geom, double distanceTolerance)
      Densifies a geometry using a given distance tolerance, and respecting the input geometry's PrecisionModel.
      Parameters:
      geom - the geometry to densify
      distanceTolerance - the distance tolerance to densify
      Returns:
      the densified geometry

    • setDistanceTolerance

      public void setDistanceTolerance(double distanceTolerance)
      Sets the distance tolerance for the densification. All line segments in the densified geometry will be no longer than the distance tolerance. The distance tolerance must be positive.
      Parameters:
      distanceTolerance - the densification tolerance to use

    • setValidate

      public void setValidate(boolean isValidated)
      Sets whether polygonal results are processed to ensure they are valid.
      Parameters:
      isValidated - true if the results should be validated

    • getResultGeometry

      public Geometry getResultGeometry()
      Gets the densified geometry.
      Returns:
      the densified geometry
