The Java Graphics 2D package makes anti-aliasing extremely easy.
Anti-aliasing is made easy by the setRenderingHint method of the Graphics2D class. Example:
BufferedImage = new BufferedImage(imageWidth, imageHeight,
Graphics2D graphics2d = bufferedimage.createGraphics();
Now, any text you draw with the Graphics2D instance you created, will be anti-aliased. This is especially nice when there is text rotation involved as it maintains the smooth text appearance that is often lost in rotation algorithms.
graphics2d.drawString("My Text", 0, 0);
Keep in mind that Graphics2D will only render the text when using the Graphics2D methods to draw the text as in the above code segment. If you create a TextLayout class, then use the draw method of your TextLayout instance to draw text on a Graphics2D object, the text will not be rendered.
