Detailed Description

template<typename InputPixelType, typename OutputPixelType, class OutputConvertTraits>
class itk::ConvertPixelBuffer< InputPixelType, OutputPixelType, OutputConvertTraits >

Class to convert blocks of data from one type to another.

ConvertPixelBuffer has a static method Convert(). It is used by itkImageFileReader to convert from an unknown type at run-time to the compile-time template pixel type in itkImageFileReader. To work with complex pixel types like RGB and RGBA a traits class is used. OutputConvertTraits() is the traits class. The default one used is DefaultConvertPixelTraits.

General method converts from one type to another.

Input values are cast to output values.

Each RGB output component is set the the input Gray value.

Weights convert from linear RGB to CIE luminance assuming a modern monitor. Values are attentuated by the Alpha channel. See Charles Poynton's Colour FAQ http://www.inforamp.net/~poynton/notes/colour_and_gamma/ColorFAQ.html

Conversion depends upon the number of components in the input. If the number of input components is 2, the output components are each set to the first input component attenuated by the second input component. This assumes that a two input pixel represents intensity and alpha. If the number of input components is not 2, the first three output components a are set to the first three input components. The remaining input components are ignored.
