    Default Flip Pictures on DrJava

    I am trying to flip a picture horizontaly but only half of it flips here is my code


    public void flipH() {
    for(int x=0;x<getWidth();x++){
    for(int y=0;y<getHeight()/2;y++){
    Pixel p= getPixel(x,y);
    Pixel newP= getPixel(getWidth()-1-x,getHeight()-1-y);
    p.setColor(newP.getColor());


    Please, I want basic answers that everyone knows. Plus I need flipping vertical too.
    }
    }
    }

    By the time you examine pixels with a big y you have already changed the "partner" pixel with a small y. And lost its old value.

    Get yourself some tiddlywinks or small colloured pieces of paper and arrange them into a rectangular pattern. Now flip the pattern. Ask yourself how you you did it. Teh codez will be along the same lines.

    You didn't return to the first thread you started.

    Why should we expect better behavior this time around?
