Is this a bug in code?

Looks like gamma correction: http://en.wikipedia.org/wiki/Gamma_correction

I guess the code is meant to be:

Code:

            srgb_alpha[0] = r < 1 ? pow(r, 2.2f) : r;
            srgb_alpha[1] = g < 1 ? pow(g, 2.2f) : g;
            srgb_alpha[2] = b < 1 ? pow(b, 2.2f) : b;
            srgb_alpha[3] = a;

But Joe can tell more I think.

OK. I could understand ganmma correction but not the code. What you've written is understandable but not the other. Thanks
