Detailed Description

template<class TPixel1, class TPixel2>
class itk::Functor::JoinFunctor< TPixel1, TPixel2 >

Join the components of two pixel types into a single pixel type.

JoinFunctor combines the components of two pixel types into a single pixel type. The components of one pixel are appended to the components of the other pixel. The output pixel type is an itk::Vector. The ValueType of the vector is the smallest scalar type that can represent the dynamic range of the both the input pixel value types. Hence, joining a char and unsigned char results in a short since that is the smallest datatype with a large enough dynamic range. To define a consistent behavior across different architectures, the join of an int and an unsigned int is float. On a 64 bit architecture, this join could be represented in a long. But on 32 bit architectures, the only safe join value type is a float. For this and similar ambiguous cases, the join value type is promoted to a float.
