Syntax

TexturePaint.createContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform xform, RenderingHints hints) has the following syntax.

public PaintContext createContext(ColorModel cm,    Rectangle deviceBounds,    Rectangle2D userBounds,    AffineTransform xform,    RenderingHints hints)

Example

In the following code shows how to use TexturePaint.createContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform xform, RenderingHints hints) method.

    for (int i = 0; i < width; i++) {
      g2.setPaint(colors[(i / 2) % colors.length]);
      g2.drawLine(0, i, i, 0);

    }
    Rectangle r = new Rectangle(0, 0, bim.getWidth(), bim.getHeight());
    tp = new TexturePaint(bim, r);
    tp.createContext(ColorModel.getRGBdefault(), new Rectangle(10, 10, 20, 20),
        null, null, null);

    Graphics2D g2d = (Graphics2D) g;
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
        RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.setPaint(tp);
    g2d.setFont(myFont);
    g2d.drawString(mesg, 20, 100);
  }
}
