well, the most immediate obvious answer would be to examine each
pixel and if it's white, do with it what you want.
however, this immediately raises the question: how do you know if
white is part of the background or part of the picture? if your
picture is well-behaved, i.e., the background is wholly outside the
picture itself, then you could use your knowledge of the row-stride
and start at each side, working your way to the middle of the
picture, stopping for that row when you reach a non-white pixel.
is that what you meant?
