  • Constructor Details

    • WarpBuilder

      public WarpBuilder(double tolerance)
      Creates a new warp builder

  • Method Details

    • setMaxPositions

      public void setMaxPositions(int maxPositions)
      Sets the maximum number of positions in the optimized grid, in case we have more we'll fall back to the warp adapter. By default there is no limit

    • isValidDomain

      public boolean isValidDomain(Rectangle2D.Double domain)
      Returns true if the given domain is valid for the splitting algorithm. Can be called before getRowColsSplit to prevent exceptions. Unlike buildWarp(MathTransform2D, Rectangle) the domain here can be expressed in geographic coordinates, so there is no requirement that the area is at least 1x1 (in geographic coordiantes, that's a massive area), but only that it's not empty
      Parameters:
      domain - domain to check

    • getRowColsSplit

      public int[] getRowColsSplit(MathTransform2D mt, Rectangle2D.Double domain)
      Given a math transform and a source domain, return the number of rows and cols by which the domain should be split to avoid transform linearity issues, or null if it could not be found.

    • buildWarp

      public Warp buildWarp(MathTransform2D mt, Rectangle domain) throws TransformException
      Parameters:
      mt - The math transform to be approximated
      domain - The domain in which the transform will be approximated
      Throws:
      TransformException
