Pannoramic Viewer 

The main software part of the virtual microscope is Pannoramic Viewer which not only enables you to view the sample but also to make annotations, measurements etc. Its functionality can be easily expanded through its various software modules. When opening Pannoramic Viewer you see all of your virtual slides in thumbnail view. Selecting one (or up to 10 at a time) the slide gets under the virtual objective of the virtual microscope. Here you can move and change the magnification of the slide very easily and fast, using the mouse. Emphasizing 'fast' is important considering the fact that the size of an average virtual slide can easily be more than 1 GB.
