    - #### paintToBufferedImage

          protected BufferedImage paintToBufferedImage(org.apache.xmlgraphics.java2d.Graphics2DImagePainter painter,
                                                       Dimension targetDimension,
                                                       int resolution,
                                                       boolean gray,
                                                       boolean withAlpha)

      Paints the image to a BufferedImage and returns that.
      Parameters:
        `painter` - the painter which will paint the actual image
        `targetDimension` - the target dimensions of the image to be converted to a bitmap
        `resolution` - the requested bitmap resolution
        `gray` - true if the generated image should be in grayscales
        `withAlpha` - true if an alpha channel should be created
      Returns:
        the generated BufferedImage

    - #### setRenderingHintsForBufferedImage

          protected void setRenderingHintsForBufferedImage(Graphics2D g2d)

      Sets rendering hints on the Graphics2D created for painting to a BufferedImage. Subclasses can modify the settings to customize the behavior.
      Parameters:
        `g2d` - the Graphics2D instance
