public RenderedImage createRendering(RenderContext rc)
Specified by:

public Rectangle2D getActualTileBounds(Rectangle2D tiledRect)


public RenderedImage createTile(RenderContext rc)
Computes the tile to use for the tiling operation. The tile has its origin in the upper left corner of the tiled region. That tile is separated into 4 areas: top-left, top-right, bottom-left and bottom-right. Each of these areas is mapped to some input area from the source. If the source is smaller than the tiled area, then a single rendering is requested from the source. If the source's width or height is bigger than that of the tiled area, then separate renderings are requested from the source.
