How to clone Image?

Question

I have an Image. I need to make a exactly copy of it and save it to BufferedImage, but there is no Image.clone(). The thing should be inside a calculating loop and so it should be really fast, no pixel-by-pixel copying. What's the best in perfomance method to do this?

Answer 1

You can draw to a buffered image, so make a blank bufferedImage, create a graphics context from it, and draw your original image to it.

BufferedImage copyOfImage = 
   new BufferedImage(widthOfImage, heightOfImage, BufferedImage.TYPE_INT_RGB);
Graphics g = copyOfImage.createGraphics();
g.drawImage(originalImage, 0, 0, null);
