    • create

      public static Oval create(double minX, double minY, double width, double height, CoordinateReferenceSystem crs)
      Creates a new Oval object.
      Parameters:
      minX - the min X ordinate
      minY - the min Y ordinate
      width - the width
      height - the height
      crs - the coordinate reference system (may be null)
      Returns:
      a new Oval object
      Throws:
      IllegalArgumentException - if either width or height are <= 0

    • createGrid

      public static SimpleFeatureSource createGrid(ReferencedEnvelope bounds, double width, double height, GridFeatureBuilder gridBuilder)
      Creates a new grid of oblongs within a bounding rectangle with grid elements represented by simple (ie. undensified) polygons.
      Parameters:
      bounds - the bounding rectangle
      width - oblong width
      height - oblong height
      gridBuilder - an instance of GridFeatureBuilder
      Returns:
      a new grid
      Throws:
      IllegalArgumentException - if bounds is null or empty; or if either width or height is <= 0; or if the CoordinateReferenceSystems set for the bounds and the GridFeatureBuilder are both non-null but different

    • createGrid

      public static SimpleFeatureSource createGrid(ReferencedEnvelope bounds, double width, double height, double vertexSpacing, GridFeatureBuilder gridFeatureBuilder)
      Creates a new grid of oblongs within a bounding rectangle with grid elements represented by densified polygons (ie. additional vertices added to each edge).
      Parameters:
      bounds - the bounding rectangle
      width - oblong width
      height - oblong height
      vertexSpacing - maximum distance between adjacent vertices in a grid element; if <= 0 or >= min(width, height) / 2.0 it is ignored and the polygons will not be densified
      gridFeatureBuilder - an instance of GridFeatureBuilder
      Returns:
      the vector grid
      Throws:
      IllegalArgumentException - if bounds is null or empty; or if either width or height is <= 0; or if the CoordinateReferenceSystems set for the bounds and the GridFeatureBuilder are both non-null but different
