为此，在FX 2.2中出现了新的快照功能。你可以说
WritableImage snapshot = scene.snapshot(null);
对于较旧的FX，您可以使用AWT机械手。这不是一个很好的方法，因为它需要启动整个AWT堆栈。
// getting screen coordinates of a node (or whole scene) Bounds b = node.getBoundsInParent(); int x = (int)Math.round(primaryStage.getX() + scene.getX() + b.getMinX()); int y = (int)Math.round(primaryStage.getY() + scene.getY() + b.getMinY()); int w = (int)Math.round(b.getWidth()); int h = (int)Math.round(b.getHeight()); // using ATW robot to get image java.awt.Robot robot = new java.awt.Robot(); java.awt.image.BufferedImage bi = robot.createScreenCapture(new java.awt.Rectangle(x, y, w, h)); // convert BufferedImage to javafx.scene.image.Image java.io.ByteArrayOutputStream stream = new java.io.ByteArrayOutputStream(); // or you can write directly to file instead ImageIO.write(bi, "png", stream); Image image = new Image(new java.io.ByteArrayInputStream(stream.toByteArray()), w, h, true, true);
