示例1: main
import sun.java2d.DestSurfaceProvider; //导入方法依赖的package包/类
public static void main(String[] args) {
GraphicsEnvironment ge =
GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
GraphicsConfiguration gc = gd.getDefaultConfiguration();
VolatileImage vi = gc.createCompatibleVolatileImage(100, 100);
vi.validate(gc);
VolatileImage vi1 = gc.createCompatibleVolatileImage(100, 100);
vi1.validate(gc);
if (!(vi instanceof DestSurfaceProvider)) {
System.out.println("Test considered PASSED: no HW acceleration");
return;

Surface s = p.getDestSurface();
if (!(s instanceof AccelSurface)) {
System.out.println("Test considered PASSED: no HW acceleration");

Graphics g = vi.createGraphics();
g.drawImage(vi1, 95, 95, null);
g.setColor(Color.red);
g.fillRect(0, 0, 100, 100);
g.setColor(Color.black);
g.fillRect(0, 0, 100, 100);

RenderQueue rq = dst.getContext().getRenderQueue();
rq.lock();
try {
dst.getContext().saveState();
dst.getContext().restoreState();
} finally {
rq.unlock();
}
// this will cause ResetPaint (it will set color to extended EA=ff,
// which is ffffffff==Color.white)
g.drawImage(vi1, 95, 95, null);
// now try filling with black again, but it will come up as white
// because this fill rect won't validate the color properly
g.setColor(Color.black);
g.fillRect(0, 0, 100, 100);
BufferedImage bi = vi.getSnapshot();
if (bi.getRGB(50, 50) != Color.black.getRGB()) {

Integer.toHexString(bi.getRGB(50, 50))+" instead of "+
Integer.toHexString(Color.black.getRGB()));
}
System.out.println("Test PASSED.");
