Hi,

I'm applying a large gaussian blur to an image and was wondering if there's a way to not have the black border appear (even after being cropped). In matlab I'd just use the border replication option in imfilter (http://www.mathworks.com/access/helpdesk_r13/help/toolbox/images/linfilt6.html). Is there a way to copy and flip an image 8 times (one for each side, and 1 for each corner), or is there a more straightforward way in quartz?

Thanks,
Mike Lewis
