* \class ConvertPixelBuffer
* \brief Class to convert blocks of data from one type to another.
*
* ConvertPixelBuffer uses itk::ConvertPixelBuffer to perform most of the
* conversions. The monoband to complex conversion is done in this class
* (different rule than in ITK). New conversions methods are also added in
* this class :
* ConvertComplexVectorImageToVectorImage
* ConvertComplexVectorImageToVectorImageComplex
* ConvertComplexToGray
*
* \ingroup OTBImageBase
