[vtkusers] Window->Image coordinate conversions?

[itkvtk123 at gmx.net]

You can do this easily with vtkImageActorPointPlacer.

This class will allow you to transform display coordinates to the corresponding image coordinates on the ImageActor.

For the actual conversion you use the method ComputeWorldPosition(...)

Where display position is the coordinate in the renderwindow and world position is the coordinate on the ImageActor.
