[slicer-users] Mouse for window/level

Since "Rotate to volume plane" was implemented, several people have been asking if 4) is a bug. I think we have the current behaviour because it was the simplest to implement, but it doesn't reflect what the users would expect (see Andriy's mail and also http://slicer-users.65878.n3.nabble.com/cutting-planes-not-orthogonal-td886549.html) and need (see http://www.na-mic.org/Mantis/view.php?id=325).

I think the following implementation would be ideal: If slice views are linked then changing orientation of any slice should change the orientation of all slices (so that the relative orientation of the slices to each other remain the same). This could work the same way for all orientation setting methods (using the reformat widget, axial/sagittal/coronal options, or rotate to volume planes).

Steve,

Thanks for fixing this! I guess this was an intermittent problem -- it
works fine now.

I was able to reproduce the other problem I reported to you yestarday.

1) load volume from Testing/Data/Input/DCE_single_serie (this is in
Slicer3 trunk)
2) link slice views
3) rotate "green" slice to volume plane
4) at this point, all slices are in axial view, rotated to volume
plane (is this a bug? to me as a user, it is a problem, so I am trying
to fix my views next)
5) unlink slice views
6) change orientation of "green" slice to sagittal
7) slices appear to be linked -- mouse over any other slice view, and
it becomes sagittal (this is a bug)
