[ITK] [ITK-users] Writing a DICOM file while preserving input image properties

I was having this same issue until I extended the GDCMImageIO class as it overrides the spacing no matter what you set in the tag. I had to copy the Write() method, and add lines similar to:

	vcl_string tmpStr;
	if ( itk::ExposeMetaData< vcl_string >( dict, "0018|0088", tmpStr ) )
	{
		m_Spacing[2] = atof( tmpStr.c_str() );
	}

before the following code:
	
	gdcm::SmartPointer<gdcm::Image> simage = new gdcm::Image;
	gdcm::Image &image = *simage;
	image.SetTransferSyntax( gdcm::TransferSyntax::ExplicitVRLittleEndian );
	image.SetNumberOfDimensions( 2 ); // good default
	image.SetDimension(0, m_Dimensions[0] );
	image.SetDimension(1, m_Dimensions[1] );
	image.SetSpacing(0, m_Spacing[0] );
	image.SetSpacing(1, m_Spacing[1] );
	image.SetSpacing(2, m_Spacing[2] );


I hope this helps,

Todd
