Class Java2DRenderer

    java.lang.Object
      org.apache.fop.render.AbstractRenderer
          org.apache.fop.render.PrintRenderer
              org.apache.fop.render.AbstractPathOrientedRenderer
                  org.apache.fop.render.java2d.Java2DRenderer

All Implemented Interfaces:
  java.awt.print.Printable, Constants, Renderer

Direct Known Subclasses:
  AWTRenderer, PageableRenderer, PNGRenderer, TIFFRenderer

    public abstract class Java2DRenderer

extends AbstractPathOrientedRenderer
implements java.awt.print.Printable

The `Java2DRenderer` class provides the abstract technical foundation for all rendering with the Java2D API. Renderers like `AWTRenderer` subclass it and provide the concrete output paths.

A lot of the logic is performed by `AbstractRenderer`. The class-variables `currentIPPosition` and `currentBPPosition` hold the position of the currently rendered area.

`Java2DGraphicsState state` holds the `Graphics2D`, which is used along the whole rendering. `state` also acts as a stack (`state.push()` and `state.pop()`).

The rendering process is basically always the same:

`void renderXXXXX(Area area) { //calculate the currentPosition state.updateFont(name, size, null); state.updateColor(ct, false, null); state.getGraph.draw(new Shape(args)); }`

Field Summary
`protected boolean` | `antialiasing` true if anti-aliasing is set
`protected int` | `pageHeight` The page height in pixels
`protected java.util.List` | `pageViewportList` List of Viewports
`protected int` | `pageWidth` The page width in pixels
`protected boolean` | `qualityRendering` true if qualityRendering is set
`protected double` | `scaleFactor` The scale factor for the image size, values: ]0 ; 1]
`protected Java2DGraphicsState` | `state` The current state, holds a Graphics2D and its context
`protected boolean` | `transparentPageBackground` false: paints a non-transparent white background, true: for a transparent background

### startRenderer

    public void startRenderer(java.io.OutputStream out)
                       throws java.io.IOException

  Initiates the rendering phase. This must only be called once for a rendering. If stopRenderer is called then this may be called again for a new document rendering.

  Specified by:
    `startRenderer` in interface `Renderer`
  Overrides:
    `startRenderer` in class `AbstractRenderer`
  Parameters:
    `out` - The OutputStream to use for output

  Signals the end of the rendering phase. The renderer should reset to an initial state and dispose of any resources for the completed rendering.

  Specified by:
    `stopRenderer` in interface `Renderer`
