Class Graphics2DRenderer

java.lang.Object
jcckit.renderer.Graphics2DRenderer
All Implemented Interfaces:
GraphicalCompositeRenderer, OvalRenderer, PolygonRenderer, RectangleRenderer, Renderer, TextRenderer
public class Graphics2DRenderer extends Object implements GraphicalCompositeRenderer, PolygonRenderer, OvalRenderer, TextRenderer, RectangleRenderer
Renderer who draws the GraphicalElements into a java.awt.Graphics2D context.

The default color for lines and texts is determined by the current color of the Graphics2D context when a new instance of Graphics2DRenderer is created.

The default font is SansSerif-12.

  • Method Details

    • init

      public Graphics2DRenderer init(Graphics2D graphics)
      Initializes this instance. During renderering the current transformation will be leaved unchanged. But the current Clip may be cleared.
      Parameters:
      graphics - Graphics2D context into which the BaiscGraphicalElements are painted.
      Returns:
      this instance.

    • startRendering

      public void startRendering(GraphicalComposite composite)
      Starts rendering of the specified composite. Does nothing except if composite has a ClippingShape. In this case the Clip of the Graphics2D context becomes the clipping rectangle determined by the bounding box of the ClippingShape.
      Specified by:
      startRendering in interface GraphicalCompositeRenderer

    • finishRendering

      public void finishRendering(GraphicalComposite composite)
      Finishes rendering of the specified composite. Does nothing except if composite has a ClippingShape. In this case the Clip of the Graphics2D context will be cleared.
      Specified by:
      finishRendering in interface GraphicalCompositeRenderer

    • render

      public void render(Polygon polygon)
      Paints the specified polygon into the Graphics2D context.
      Specified by:
      render in interface PolygonRenderer

    • render

      public void render(Rectangle rectangle)
      Paints the specified rectangle into the current Graphics context.
      Specified by:
      render in interface RectangleRenderer

    • render

      public void render(Oval oval)
      Paints the specified oval into the current Graphics context.
      Specified by:
      render in interface OvalRenderer

    • render

      public void render(Text text)
      Paints the specified text into the current Graphics context.

      If the font size is zero the default font size will be used.

      If the orientation angle is unequal zero the text will first be painted into an off-screen image and rotated. Finally, it will be drawn into the current Graphics context. Note, that only integer multiples of 90 degree rotation are performed. Other orientation angles will be adjusted to the nearest integer multiple of 90 degree.

      Specified by:
      render in interface TextRenderer
