- /**
- * This is an implementation of a FOP Renderer that renders areas to AFP.
- * <p>
- * A renderer is primarily designed to convert a given area tree into the output
- * document format. It should be able to produce pages and fill the pages with
- * the text and graphical content. Usually the output is sent to an output
- * stream. Some output formats may support extra information that is not
- * available from the area tree or depends on the destination of the document.
- * Each renderer is given an area tree to render to its output format. The area
- * tree is simply a representation of the pages and the placement of text and
- * graphical objects on those pages.
- * </p>
- * <p>
- * The renderer will be given each page as it is ready and an output stream to
- * write the data out. All pages are supplied in the order they appear in the
- * document. In order to save memory it is possible to render the pages out of
- * order. Any page that is not ready to be rendered is setup by the renderer
- * first so that it can reserve a space or reference for when the page is ready
- * to be rendered.The renderer is responsible for managing the output format and
- * associated data and flow.
- * </p>
- * <p>
- * Each renderer is totally responsible for its output format. Because font
- * metrics (and therefore layout) are obtained in two different ways depending
- * on the renderer, the renderer actually sets up the fonts being used. The font
- * metrics are used during the layout process to determine the size of
- * characters.
- * </p>
- * <p>
- * The render context is used by handlers. It contains information about the
- * current state of the renderer, such as the page, the position, and any other
- * miscellaneous objects that are required to draw into the page.
- * </p>
- * <p>
- * A renderer is created by implementing the Renderer interface. However, the
- * AbstractRenderer does most of what is needed, including iterating through the
- * tree parts, so it is this that is extended. This means that this object only
- * need to implement the basic functionality such as text, images, and lines.
- * AbstractRenderer's methods can easily be overridden to handle things in a
- * different way or do some extra processing.
- * </p>
- * <p>
- * The relevant AreaTree structures that will need to be rendered are Page,
- * Viewport, Region, Span, Block, Line, Inline. A renderer implementation
- * renders each individual page, clips and aligns child areas to a viewport,
- * handle all types of inline area, text, image etc and draws various lines and
- * rectangles.
- * </p>
- *
- * Note: There are specific extensions that have been added to the FO. They are
- * specific to their location within the FO and have to be processed accordingly
- * (ie. at the start or end of the page).
