<DIV><SPAN class=717175523-22032005><FONT face=Arial size=2>Hi, this might be a
simple question but I havn't found a good solution yet. I am going to use
RegionOfInterestImageFilter to extract a region for processing, say canny edge
detection. However, after processing, I want to display it with the
original image in fltkimageviewer. It seems that the imageviewer requires
the overlay image the same size as the original image? So I would create a empty
image with the same size as the original image and fill the processed region
back in. I could use iterators and fill in pixel by pixel. I am
wondering if there is any filter designed already for this purpose? Or sth
involving with <EM><FONT
size=3>SetFixedImageRegion?</FONT></EM></FONT></SPAN></DIV></FONT></DIV></BODY></HTML>
