Mapping the Screen to the Tablet – the Viewport
Viewport only applies when the tablet is in tablet mode. The viewport is in the area of the
tablet that is directly correlated or mapped to the computer screen. This direct mapping of
the tablet and screen is what gives you the ability to trace or draw with precision.
When moving the stylus/cursor inside the viewport, the pointer tracks with it. However,
when you maneuver the stylus/cursor out of the viewport, the pointer stops at the screen
edge.
The Default Viewport
The default viewport is:
PixScale:
Offset: X = 72 screen pixels per tablet inch
Y = 72 screen pixels per tablet inch
X = 1.0 inch from left edge of tablet active area
Y = 1.0 inch from top edge of tablet active area
