#include <itkJoinImageFilter.h>

Detailed Description

template<typename TPixel1, typename 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.

Member Function Documentation

template<typename TPixel1 , typename TPixel2 >
void itk::Functor::JoinFunctor< TPixel1, TPixel2 >::FirstCopier ( JoinType out,
unsigned int  idx,
const TPixel1 &  A 
) const
inlineprivate

Copier function to copy the first pixel to the output pixel casting as necessary. The contents of the source pixel are placed in the output pixel at position idx. This method simply delegates to one of two overloaded implementations based on the dimension (or number of components) of the first pixel. FirstCopier() and SecondCopier() are defined as distinct functions (as opposed to being a single Copier() function overloaded on the last parameter type or pixel type) to avoid "already declared/defined" errors for the case where TPixel1 and TPixel2 are the same types.
