[Insight-users] gdcm 2.0 - single tag/key

[Rashindra Manniesing]

HI Mathieu,

Thanks!

I was referring to Utilities/DICOM/DICOMApphelper and other files in that
directory (eg DICOMParser) - they are used in eg itkDICOMImageIO2.

What is dicomapphelper ? there is no such beast in gdcm AFAIK.

In ITK/GDCM:

    std::string tagkey = "0008|1050";
    std::string labelId;
    if( itk::GDCMImageIO::GetLabelFromTag( tagkey, labelId ) )
      {
      std::string value;
      std::cout << labelId << " (" << tagkey << "): ";
      if( dicomIO->GetValueFromTag(tagkey, value) )
        {
        std::cout << value;
        }
      else
        {
        std::cout << "(No Value Found in File)";
        }
      std::cout << std::endl;
      }
    else
      {
      std::cerr << "Trying to access inexistant DICOM tag." << std::endl;
      }
