hi
I have been having some problems using the image IO to read in a variety =
of file types, specifically VTK and Meta data files. Using the code =
below to read in 3D data (both VTK and meta files):
typedef itk::Image<unsigned char, 3> InputITKImageType;
typedef itk::ImageFileReader<InputITKImageType> ImageFileReaderType;
reader =3D ImageFileReaderType::New();
itk::VTKImageIOFactory::RegisterOneFactory();
itk::MetaImageIOFactory::RegisterOneFactory();=20
reader->SetFileName(lpszPathName);=20
try
{
reader->Update();
}
catch (itk::ImageFileReaderException &e)
.
.
.
an exception is thrown:
Number of dimensions in file (2) does not match number of dimensions in =
output (3).=20
However, i am sure that the files are 3D data. The code also fails if I =
force the ImageFileReader to use a specific imageIO such as =
itkVTKImageIO or itkMetaImageIO.
Has anyone else encountered any similar problems? ideas?
thanks,
wilson
