Dear List,
I was trying to apply some RGBA image interaction between mitk and itk using
the mitk::DataStorage and thus the CastToItkImage function of mitkImageCast.h.
I figured out, that all functions are defined for itk::Image with
itk::RGB<uchar> pixels. But unfortunately explicit functions for
itk::RGBA<uchar> are missing.
I don't know where to send the change request so I just write this mail.
This following code to enable itk::RGBA casting can and should be included in
the mitkImageCastPart4.cpp for future mitk versions.
typedef itk::Image<itk::RGBAPixel<unsigned char>, 2> itkImageRGBAUC2;
typedef itk::Image<itk::RGBAPixel<unsigned char>, 3> itkImageRGBAUC3;
namespace mitk
{
template <> void CastToItkImage<itkImageRGBAUC2>(const mitk::Image * mitkImage,
itk::SmartPointer<itkImageRGBAUC2>& itkOutputImage)
{
typedef itkImageRGBAUC2 ItkOutputImageType;
AccessFixedTypeByItk_1(mitkImage, _CastToItkImage2Access,
(itk::RGBAPixel<unsigned char>),
(::itk::GetImageDimension<ItkOutputImageType>::ImageDimension), itkOutputImage);
}
template <> void CastToItkImage<itkImageRGBAUC3>(const mitk::Image * mitkImage,
itk::SmartPointer<itkImageRGBAUC3>& itkOutputImage)
{
typedef itkImageRGBAUC3 ItkOutputImageType;
AccessFixedTypeByItk_1(mitkImage, _CastToItkImage2Access,
(itk::RGBAPixel<unsigned char>),
(::itk::GetImageDimension<ItkOutputImageType>::ImageDimension), itkOutputImage);
}
}
Regards,
Matthias
