You should not have to call Update if it is in the pipeline. Maybe this
is a bug?<br><br>

Thank you for the hint, this solved the problem! Now it shows the correct
scalar type. <br>
In the case of getting the ScalarType just after using
vtkImageChangeInformation it is obvious that one has to call Update(),
but what I don’t understand <br>
is that you still need to manually call update() on
ImageChangeInformation when using it in a pipeline. <br>
I always thought the “Sink” class (in this case vtkImagePlaneWidget)
would automatically call update() for the whole pipeline anyway when
being Enabled and rendered in the RenderWindow. <br>
Also without calling Update() I could actually see the resliced Volume
(but not shown correctly) on the plane and didn’t get an error
message.<br>
Anyway now it’s correct. Thanks again.<br>
<br>
