Deleting a BufferedImage drawn on another BufferedImage

I have a BufferedImage called originalImage that is drawn on a JPanel. I have an array of BufferedImage called layer and I draw all of those layer on the originalImage

So how can I delete (for example) layer[0] entirely from the originalImage ?

You need to save the position where you draw your BufferedImage (e.g. layer[0]). Then you can just overpaint this:

public void overpaintImage (BuffereImage originalImage, Point imagePos, Dimension imageSize)
{
    Rectangle r = new Rectangle(imagePos.x, imagePos.y, imageSize.width, imageSize.height);
    Graphics2D g = originalImage.createGraphics();
    g.setColor(Color.WHITE); // or whatever your background color is
    g.fill(r);
}

Simple answer: you can't! Just delete one layer entry and paint everything new. It's at low cost, so don't worry.
