The class QmitkCreateMultiLabelSegmentationAction provides a function "Run" that performs the action - which is to create a new multilabel segmentation out of a given reference image. While working on T28142: [Segmentation] Remove plugin redundancy with MultiLabelSegmentation and T26396: [Segmentation] Refactor functions to create new (empty) segmentations I realized that the function does not distinguish between static and dynamic segmentations (as it is typically done when creating a new segmentation using the "New" button in the (MultiLabel) Segmentation plugin view).
It always creates a dynamic segmentation, taking the original reference image into account.
Currently I'm not sure where this class is actually used.
