Here we demonstrate how to use spline segmentation ROI tools on multiple viewports (stack and volume), segmentations and different styles for active and inactive states
Select a segmentation index
Select a spline curve type
Draw a spline curve on one or more viewports
Left: axial/stack
Right: coronal/volume
Middle: sagittal/volume
Repeat the steps 1-3 as many times as you want
Notice that each segment index has a different color assigned to it
Change the style for the current segmentation
Change the style for both scenarios, active and inactive, as desired
Click on "Add Segmentation"
The new segmentation shall be the active one
Confirm the active/inactive style is applied properly
