问题描述
我创建了一个 JFrame,它为游戏加载外部小程序,如下所示:
I created a JFrame that loads an external applet for a game like so:
//Setup everything for the Stub.. Below adds the stub to the applet and creates it.
DownloadFile(new URL(World + "/" + Archive), "./gamepack.jar");
CAppletStub Stub = new CAppletStub(new URL(World), new URL(World), this.Parameters);
applet = (Applet) new URLClassLoader(new URL[] {new URL(World.toString() + "/" + Archive)}).loadClass("Rs2Applet").newInstance();
applet.setStub(Stub);
applet.init();
applet.start();
applet.setPreferredSize(new Dimension(Width, Height));
Frame.getContentPane().add(applet);
我正在尝试截取此小程序的屏幕截图或让它在 BufferedImage 中绘制其表面.我尝试将Applet"子类化并将我的 URLClassLoader 转换为该类,但它无法转换,这是有道理的.
I'm trying to screenshot this applet or get it to draw its surface in a BufferedImage. I tried subclassing "Applet" and casting my URLClassLoader to that class but it can't cast which makes sense.
如何捕获小程序渲染到图像中的所有内容?
How can I capture everything the applet is rendering into an Image?
推荐答案
这适用于任何组件,而不仅仅是小程序:
This works for any Component, not only Applets:
public static BufferedImage toBufferedImage(Component component) {
BufferedImage image = new BufferedImage(component.getWidth(),
component.getHeight(), BufferedImage.TYPE_INT_RGB);
Graphics g = image.getGraphics();
component.paint(g);
return image;
}
