[Insight-users] pixel type -- slcalar or non-scalar?

[Julien Jomier]

Hi Patrick,

This is correct. ITK doesn't have a general way of initializing both 
scalar and vector type at this point. You can initialize scalar and 
RGBPixel in the same function, but you have to create a separate 
function/class for images of vectors.

Hope that helps,

Julien
