Hi,
I've written a short program to flood fill a simple black and white image of the outline of a cell (I'm using ImageJ). The image is too big to do this recursively (about 400x400 pixels) so I've used queues. However, my program only runs for a short while and then returns and out of memory error. I'm really not sure why it ends up using an upwards of 400MB of memory before it crashes.
Thanks,
-Colin

Is this an Eclipse question?

There are really far better forums for Java questions like JavaRanch,
stackOverflow and JGuru. Glad you figured it out!
