Antialiased fonts

By default, anti-aliasing is disabled for better performance. This is not so noticeable until you start transforming images or using fonts in perspective. To activate anti-aliasing (and a good interpolation method), set the rendering hints in the Graphics2D object you are using.

 Graphics2D g=(Graphics2D) bi.getGraphics();
 g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BICUBIC);
 g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
