[Insight-developers] Link errors and itk::NumericTraits on Windows

[Julien Jomier]

Hi Zach,

Some of our programs using ITK need to know the minimum/maximum pixel 
values. Before your implementation we defined our own NumericTraits for 
RGBPixel with max() of RGBPixel<unsigned char> being the max of unsigned 
char, etc...
With the current implementation of numeric traits for RGBPixel, there is 
no way to know the maximum of the pixel type. One option is to add the 
min() and max() functions returning the min and max of the actual type 
(i.e unsigned char/unsigned short), but I don't know if it's correct 
though. I'm open to suggestions here.

Also, do you plan to add RGBA pixel traits too?

Thanks,

Julien
