    Modifier and Type Method Description
    int[] contour()
    Return a map of simple contours.
    boolean getData​(java.lang.String survey)
    Get the data for the contourer
    double[] getRange()  
    void putImage​(Image img)  
    void setFunction​(java.lang.String funcName)
    Set the transformation to be done on the input image before finding contour regions.
    void setLimits​(double min, double max, int n)  
    void setLimits​(double min, double max, int n, double fraction)

    • setLimits

      public void setLimits​(double min, double max, int n)
    • setLimits

      public void setLimits​(double min, double max, int n, double fraction)
      Set up the limits for the contouring. Note that if logarithmic contours are desired, then the limits should be the common logs of the limits. E.g., if you want to do 5 intervals with the first at 1 and the last at 100, then enter limits of 0 and 2.
    • putImage

      public void putImage​(Image img)
    • getData

      public boolean getData​(java.lang.String survey)
      Get the data for the contourer
    • getRange

      public double[] getRange()
    • setFunction

      public void setFunction​(java.lang.String funcName)
      Set the transformation to be done on the input image before finding contour regions.
      Parameters:
      funcName - The string "sqrt" or "log" Note that log implies common logarithms.
    • contour

      public int[] contour()
      Return a map of simple contours. The contour value for each pixel in the image is computed. When two adjacent pixels are in different contour regions a contour is drawn in the pixel whose value is closest to the contour value.
      Returns:
      An integer array which gives the contour that should be drawn on any given pixel.
