Question

How can I save BufferedImage with TYPE_INT_ARGB to jpg?

Program generates me that image:

Answer 1

OK! I've solved it. Everything was pretty easy. Don't know is it a good decision and how fast it is. I have not found any other. So.. everything we need is define new BufferedImage.

BufferedImage buffImg = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = buffImg.createGraphics();

// ... other code we need

BufferedImage img= new BufferedImage(buffImg.getWidth(), buffImg.getHeight(), BufferedImage.TYPE_INT_RGB);
Graphics2D g2d = img.createGraphics();
g2d.drawImage(buffImg, 0, 0, null);
g2d.dispose();

If there any ideas to improve this method, please, your welcome.
