Java Graphics2D.getDeviceConfiguration（）的奇怪行为

这是我的程序草图，用于说明问题：

view = getGraphicsConfiguration().createCompatibleImage(100, 100);

// creating a BufferedImage with size 100x100

Rectangle r = view.createGraphics().getDeviceConfiguration().getBounds();

// this correctly returns a rectangle of 100x100, as in my understanding the device
// is the BufferedImage and its size is 100x100

/* Later a new object is created, where 'view' again is assigned, so it is a different instance variable (even if it were the same object, I would not understand the behavior). */

view = getGraphicsConfiguration().createCompatibleImage(200, 200);

// creating a BufferedImage with size 200x200

Rectangle r = view.createGraphics().getDeviceConfiguration().getBounds();

// now this again returns a rectangle of 100x100, though I would expect it to return
// 200x200 (!?), for some reason the system seems to remember the old settings?

我检查了上面对getDeviceConfiguration的两次调用返回的GraphicsConfiguration。它是同一个物体

谢谢你的评论

view.getWidth和view.getHeight返回什么？什么是getGraphicsConfiguration？getWidth和getHeight返回正确的值，我做了一个简单的测试并验证了结果，我不确定我是否担心，当我这样做时，总是以这种方式创建图像，并依赖于getWidth和getHeight值……但这只是megeGraphicsConfiguration返回X11GraphicsConfig[dev=X11GraphicsDevice[screen=0]，vis=0x21]
