如何用java读取屏幕图象

如何使用java读取屏幕上（x1,y1）到（x2,y2）的图象？
请大虾指点！谢谢！

Answer 1

大概思路就是下面这样了width=|x1-x2|,high=|y1-y2|
class ScreenCapture
{
/**
* @param args
*/
private Robot robot = null;
private Rectangle scrRect = null;
int x1,y1;
int width,high;

public ScreenCapture()
{
try
{
robot = new Robot();
}
catch (Exception ex)
{
System.out.println(ex.toString());
}
scrRect = new Rectangle(x1, y1, width, height);
}

public BufferedImage captureScreen()
{
BufferedImage bufImg = null;

try
{
bufImg = robot.createScreenCapture(scrRect);

}
catch (Exception e)
{
System.out.println(e.toString());
}
return bufImg;
}
}
