Two important types that come with the Image Processing Extension are ImgPlusValue and LabelingValue. They wrap an n-dimensional image or labeling, respectively. If a table column is, for instance, of type ImgPlusValue, then all corresponding cells of that column are essentially images. These images do not have to be of the same type, dimension etc. In the table view of an according output port only the first plane (actually a smaller thumbnail) of the possibly multidimensional image/labeling will be rendered. Beside this a string representation is available, too, that helps to have a glance at the metadata of an image or labeling. It can be shown by a right mouse-click on the respective column header in the table view. A table containing an image and labeling column are shown in Figure 3.
