我想保存整个帧的截图,但我的问题是当我尝试使用我当前的代码执行此操作时,如果我将框架的大小设置得更小,那么我只能保存可见的框架部分.
BufferedImage myImage = new BufferedImage(1250, 950,BufferedImage.TYPE_INT_RGB );
frame.paintAll(myImage.createGraphics());
try{
ImageIO.write(myImage, "jpg", new File(fileChooser.getSelectedFile().toString() + ".jpg"));
}catch (IOException exception){
exception.printStackTrace();
}
解决方法:
Java GUI组件的绘制方法仅在屏幕上可见或需要重新绘制的剪切区域中绘制.
试试这个hack：创建Graphics2D包装器对象,它将所有方法调用转发给实际的Graphics2D实例但不允许更改剪切区域.
你需要做的是：

import java.awt.Composite;

然后在你的代码中：
BufferedImage myImage = new BufferedImage(1250, 950,BufferedImage.TYPE_INT_RGB );
Graphics2D delegate = myImage.createGraphics();
delegate.setClip(0,0,1250,950);
Graphics2D graphics = new Graphics2DWrapper(delegate);
frame.paintAll(graphics);
try{
ImageIO.write(myImage, "jpg", new File(fileChooser.getSelectedFile().toString() + ".jpg"));
}catch (IOException exception){
exception.printStackTrace();
}
试一试,告诉我们它是否有效.
