Class Tea

  • All Implemented Interfaces:
    Serializable, Component

    public class Tea
    extends Projecter
    This class provides for the translation between coordinates and the TEA Equal Area projection.

    The projection is centered at the north pole. The south pole is projected to the four corners at (+/-1, +/-1). The equator projects to the diagonals running between the points (-1,0)->(0,1), (0,1)->(1,0), (1,0)->(0,-1), (-1,0)->(0,-1). These diagonals divide the four unit squares at the center of the coordinate grid into 8 right isoceles triangles.

      • isInverse

        public boolean isInverse​(Transformer obj)
        Description copied from class: Transformer
        Are these two transformations, inverses of each other? This method is used to optimize a series of transformations where transformations.
        Specified by:
        isInverse in class Transformer
      • transform

        public void transform​(double[] unit,
                              double[] plane)
        Description copied from class: Transformer
        Convert a single point where the output vector is supplied.
        Specified by:
        transform in class Transformer
        Parameters:
        unit - The input vector.
        plane - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.
      • straddleable

        public boolean straddleable()
        Description copied from class: Projecter
        Is it possible for a pixel to straddle the valid region.
        Overrides:

      • straddle

        public boolean straddle​(double[][] vertices)
        Description copied from class: Projecter
        Does this pixel go wrap around the standard region of the image? E.g., does it straddle the 180 deg in a Car or Ait projection?
        Overrides:
        straddle in class Projecter
      • straddleComponents

        public double[][][] straddleComponents​(double[][] vertices)
        Description copied from class: Projecter
