Pixel information has been removed with {D686}. We discussed that we will open a new task to add a simple pixel value information view as a separate task.

{D722} also belongs to this task but might not be finished this week.

I added another fix to have a simple datanode context menu with a reinit and reset-geometry action for render-window specific initialization.

The effect using the MxNMultiWidget

{D722} is a proposed change for checking the render window geometry and give the user a warning if the geometry is not aligned with the selected reference geometry.
The effect can be seen here:

I created a first working version, based on @s434n's branch (see above). I created an integration branch, made some changes and rebased everything to the latest develop.
Now the following changes, which are already merged into develop, are included, since the integration branch is based on e4d0b1591a17054b4c6792c235aa41345b842cb7:

• T27613: Improve reinit behavior / {D675}
• T26496: [mxn multi widget] Re-initializations reset all render windows / {D708}
• {T26627} / {D714}

The idea was to provide an additional differential here for this task that adds the test so yes, the code is there and will be visible in the differential.

I added the PR (https://github.com/MITK/MITK/pull/262/) as a differential.

I quickly looked into this using the experimental state of the mxnMultiWidget but I get a Workbench crash. This might be unrelated so I tested something else:
I used the StdMultiWidget, loaded Pic3D but then I used the Render Window Manager to change the Mapper of the axial render window from 2D Mapper to 3D Mapper.
I get the following crash:

@floca @s349i I removed the large T28524: Refactor LabelSetImage and associated classes. task as a subtask so this tree of subgraphs looks cleaner.
@s349i We can clean up / go through the subtasks once your changes are under review / are reviewed.
