在Java中绘制Bufferedimage时出错

Question

I am trying to draw a BufferedImage using Java graphics. In my previous experiences, it worked many times, but now I don't know why eclipse is giving me an error.

It gives me this error:

The method drawImage(BufferedImage, int, int, null) is undefined for the type Graphics

public void render(Graphics g){

    g.drawImage(ss1[1],30,80,null);
}

In the above code, ss1[] is an array of BufferedImage

Answer 1

That error means that there is not a method with that signature.

Are you sure there is a drawImage that accepts a BufferedImage , an int , another int and Object ?

Answer 2

There is a method drawImage(Image, int, int, ImageObserver) in Graphics - which should match your call as pointed out by @MadProgrammer.

I suggest you try to call Graphics2D#drawImage(BufferedImage img, BufferedImageOp op, int x, int y) .

As Graphics is usually a Graphics2D, you should be able to call

((Graphics2D)g).drawImage(ss1[1],null, 30,30);

While I am unsure if you can leave the ImageOp null.

Hm, but maybe your issue is rather the same as this person's? Can't draw a Buffered Image
