Hi Chris.

You can do something like...

// dicom tag
std::string windowWidthTagKey;
std::string windowCenterTagKey;

// dicom tag string values...

windowWidthTagKey = "0028|1051"
windowCenterTagKey="0028|1050";

//extract the dictionary
itk::MetaDataDictionary & dict = m_ImageIO->GetMetaDataDictionary();

// extract windowWidth value
if ( itk::ExposeMetaData<std::string>(dict,windowWidthTagKey,windowWidth))
{
std::cout << "Window width tag value" << windowWidth << std::endl;
}
else
{
std:cerr << " Window width tag not found!" << std::endl;
}

// Something similar for window center also...

Give it a shot and let us know if you encounter any problems....
