      Returns:
      the GOCA graphics object

    • setGraphicsObject

      public void setGraphicsObject(GraphicsObject obj)
      Sets the GOCA graphics object
      Parameters:
      obj - the GOCA graphics object

    • getPaintingState

    • setGraphicContext

      public void setGraphicContext(org.apache.xmlgraphics.java2d.GraphicContext gc)
      Sets the GraphicContext
      Parameters:
      gc - GraphicContext to use

    • convertToAbsoluteLength

      public double convertToAbsoluteLength(double length)
      Converts a length value to an absolute value. Please note that this only uses the "ScaleY" factor, so this will result in a bad value should "ScaleX" and "ScaleY" be different.
      Parameters:
      length - the length
      Returns:
      the absolute length

    • applyStroke

      protected void applyStroke(Stroke stroke)
      Apply the stroke to the AFP graphics object. This takes the java stroke and outputs the appropriate settings to the AFP graphics object so that the stroke attributes are handled.
      Parameters:
      stroke - the java stroke

    • draw
