    • setScale

      public void setScale(double scale)
      Sets the value for the amount of scaling to be done along both axes.
      Parameters:
      scale - Scale factor
      Since:
      2.0
    • setScale

      public void setScale(double x, double y)
      Sets the value for the amount of scaling to be done along X and Y axes individually.
      Parameters:
      x - Amount of scaling on X axis
      y - Amount of scaling on Y axis
      Since:
      2.0
    • setRotation

      public void setRotation(double angle)
      Sets the rotation angle.
      Parameters:
      angle - Angle of rotation
      Since:
      2.0
    • setTranslation

      public void setTranslation(double x, double y)
      Sets the translation amounts for both axes.
      Parameters:
      x - Amount of shift on X axis
      y - Amount of shift on Y axis
      Since:
      2.0
    • getTransformed

      public Point getTransformed(Point p)
      Returns a new transformed Point of the input Point based on the transformation values set.
      Parameters:
      p - Point being transformed
      Returns:
      The transformed Point
      Since:
      2.0
