  • Method Details

    • draw

      void draw(Rendering rendering, FigureStyle style)
      Draws the symbol on the given rendering using the given style. The rendering's graphics is transformed so that drawing can be done directly in symbol coordinates using view units, e.g. 
           rendering.getGraphics().draw(symbolShape);
      or 
           rendering.getGraphics().drawRenderedImage(symbolImage, null);
      Parameters:
      rendering - The rendering.
      style - The style.

    • isHitBy

      boolean isHitBy(double x, double y)
      Tests weather this symbol is hit by the given point.
      Parameters:
      x - The X-coordinate of the point in symbol coordinates using view units.
      y - The Y-coordinate of the point in symbol coordinates using view units.
      Returns:
      true, if so.

    • getBounds

      Rectangle2D getBounds()
      The bounds of the symbol.
      Returns:
      The bounds of the symbol in symbol coordinates using view units.
