Paint, but there are others, such as
This code will create a
TexturePaint like the blue line pattern in your example:
BufferedImage texture = new BufferedImage(1, 30, BufferedImage.TYPE_INT_RGB); Graphics2D g = texture.createGraphics(); g.setColor(Color.white); g.fillRect(0, 0, 1, 30); g.setColor(new Color(0x26A2D6)); g.fillRect(0, 0, 1, 20); g.dispose(); TexturePaint texturePaint = new TexturePaint(texture, texture.getRaster().getBounds());
You can then pass that
texturePaint as the argument to
