[Insight-users] Getting RGBPixel value with ImageRegionIteratorWithIndex

[Olivier Rousseau]

Hi,

I have a simple question, but I couldn't find the answer. I have a
ImageRegionIteratorWithIndex that iterates over a RGB Image.
How can I extract (and change) the Red values (or Green, or Blue)
of the Pixel?

Thanks!
Olivier
