Please keep the discussion on the list. It looks like you're missing the
part about making the points into an ImageType::IndexType -

  ImageType::IndexType corner1 = region.GetIndex();
  ImageType::IndexType corner2;
  corner2[0] = corner1[0] + region.GetSize()[0] - 1;
  corner2[1] = corner1[1] + region.GetSize()[1] - 1;

  itk::LineIterator<ImageType> it(image, corner1, corner2);
