[Insight-users] returning a smart pointer from a function

[Ricardo Ferrari]

Hi guys,

I am just wondering if is there any disadvantage in using the following
function to encapsulate the image file reading.

Thank you,
Ricardo


///

template< typename TImageType >
typename TImageType::Pointer ReadImage( const std::string fileName )
{
    typedef itk::ImageFileReader< TImageType >    ImageFileReader;
    typename ImageFileReader::Pointer reader = ImageFileReader::New();
    reader->SetFileName( fileName );

    try
    {
        reader->Update();
    }
    catch (... )
    {
        std::cout << "Error while reading in image" << fileName <<
std::endl;
        throw;
    }

    return reader->GetOutput();
}


The function is used as follows:

InputImageType::Pointer img = ReadImage< InputImageType >( inputFileName );
