Create png image file

[Tim]

I'm trying to read a png image file, change some colors, and write it back
out to a file.
My code so far is below. Can anyone tell me (specifically - details please)
how to write the modified pixels out to a new file or change the existing
file and save the change? Every time I try to write it out the color
changes don't show up, even if I just set all pixels to black.

Thanks,
Tim

File imgFile = new File("myImage.png");

// get BufferedImage
BufferedImage image = ImageIO.read(imgFile);

int x = image.getMinX();
int y = image.getMinY();
int w = image.getWidth();
int h = image.getHeight();

// get image pixels
int[] oldPixels = new int[w * h];
PixelGrabber grabber = new PixelGrabber(image, x, y, w, h, oldPixels, 0,
w);

// modify pixels
int[] newPixels = replaceColor(oldPixels);

// NOW WHAT? How to write to a file?

You've already asked this question a few days ago, and the answer has
remained the same. Can you stop asking this question when you've been given
the answer???

Yes, we know. You already asked that question. What was wrong with the
first answerers, and how often do you intend to ask the same question?
