Two Problems:
mitkImagePixelReadAccessor.h Line 90 and following:
"PixelAccessorType" is not defined. It should be "ImagePixelAccessorType". It's a Typo.
When you create a imagePixelReadAccessor, you will get the exception “Invalid ImageAccessor: PixelTypes of Image and ImageAccessor are not equal”, even though the pixeltypes are the same.
Problem is mitkImagePixelReadAccessor.h Line 80:
if(!( m_ReadAccessor.m_Image->GetPixelType() != mitk::MakePixelType<itk::Image<TPixel, VDimension> >()) )
{
mitkThrow() << "Invalid ImageAccessor: PixelTypes of Image and ImageAccessor are not equal";
}In the if-statement the != should actually be a ==. Also a Typo.
