Hi Klaus, I used the way you describe with RGBAPixel<unsigned char> and it works fine. But I want to change the intensity of a color channel. E.g. multiply with 0.8 to reduce the intensity or set some single voxel into another color. When I cast the mitkImage to a itkImage I get a runtime error (wrong data format from some cryptic typedef to itkImage<TPixel, ...>). When I read the details from application, I get "N3itk9RGBAPixelIhEE" as PixelType. Is there an other way to cast mitk to itk image or change single voxels?
