[Insight-users] Setting fixed image

[Christoph Palm]

Hi Tony,

unfortunately I didn't work with meshes and points before.
Nevertheless, I would say, that it makes now sense to
build up a new PointsContainer object with

> PointsContainer::Pointer pointsContainer = PointsContainer::New();

According to the documentation, mesh->GetPoints() results in a
PointsContainer* , so I would try

PointsContainer *pointsContainer = mesh->GetPoints();

Regards

Christoph
