With the VS-viewer you can view the whole slide with high resolution
and a stepless zoom. The VS-Viewer is only loading the image information
from the actual field of view and their adjacent images ("prefetching").
This enables an efficient viewing speed.
Zooming is done with the + or - button in the "Toolbar"
(bottom left). Alternatively you can use "Shift" or "A"
on the keyboard for zooming in (magnifying) respectively "Ctrl"
or "Z" for zooming out (demagnifying). Panning is done
with the arrows
on the "Toolbar", with the mouse (left-click in the image,
hold and move) or with the arrow keys on the keyboard. With a click
get back to the initial zoom.
In the left top corner there is an overview image of the whole slide
("NavWindow"). The red rectangle is showing the actual field of
view and is useful for orientation on the slide. A moving of the
rectangle with the mouse enables a fast and direct change to a specific
position of the slide at higher magnifications.
