The zoom tool
is present in all 2D edition tools, namely Automatic
contour detection, Contour and dot set
edition, Slice alignment, and Mosaic.
It is important to notice that all BioVis3D features are fully functional
at any level of zoom, thus, the zoom tool helps with the
visualization and the operation of the piece of data the user is working
with (e.g. a contour, a slice, an image of a mosaic)
As soon as a slice is opened, a zoom factor is applied to make it fit the window. The applied
zoom factor is shown in the Zoom Factor Combo Box as illustrated in Figure 1.
