Image image = ImageIO.read(new File(file));BufferedImage buffered = (BufferedImage) image;在我的程序中，我嘗試：final float FACTOR = 4f;BufferedImage img = ImageIO.read(new File("graphic.png"));int scaleX = (int) (img.getWidth() * FACTOR);int scaleY = (int) (img.getHeight() * FACTOR);Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);BufferedImage buffered = (BufferedImage) image;不幸的是，我得到運行時錯誤：sun.awt.image.ToolkitImage無法轉(zhuǎn)換為java.awt.image.BufferedImage顯然，投射不起作用。問題是：將Image轉(zhuǎn)換為BufferedImage的正確方法是（或存在）什么？

從Java游戲引擎：
/**
* Converts a given Image into a BufferedImage
*
* @param img The Image to be converted
* @return The converted BufferedImage
*/
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;
}
