Java将图像转换为BufferedImage

从Java游戏引擎：

public static BufferedImage toBufferedImage(Image img){    if (img instanceof BufferedImage)    {        return (BufferedImage) img;    }    // Create a buffered image with transparency    BufferedImage bimage = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);    // Draw the image on to the buffered image    Graphics2D bGr = bimage.createGraphics();    bGr.drawImage(img, 0, 0, null);    bGr.dispose();    // Return the buffered image    return bimage;}
