160 Chapter 9 Displays
Rotation. Rotates the display to an arbitrary angle. This allows you to use a
vertical display format, as well as other creative display arrangements as
shown in the illustration under “Alternative Display Layouts” on page 10.
◆ NOTE: Edge blending will only work properly between displays that are on
the same stage tier with the same rotation angle and stage size.
Stage Position of Display Center. This field is similar to the Left and
Top fields in the “Stage Position of Display” field above, but indicates the
center of the display rather than the top left corner. The center is often more
relevant when the display is rotated to an arbitrary angle.
GEOMETRY CORRECTION These settings allow you to compensate for any errors caused by projection off-
axis (perspective), on a curved surface or for minor optical distortion.
◆ NOTE: Projecting straight from the front on a flat surface always gives the
best image. Use geometry correction only when absolutely necessary.
The numeric fields at the bottom of the dialog box show values corresponding
to the currently selected point and handle. The buttons next to each numeric
field adjust the value with single pixel accuracy.
◆ HINT: Go online before opening the Display dialog box to see the changes
on screen as you make them.
Corner Shapes. Adds bezier handles to the corners, allowing you to
compensate for minor optical distortion, often associated with wide-angle
lenses (as exemplified on page 249).
Constrain Points. Limits the freedom by which points can be moved to keep
them within realistic bounds. For example, it doesn’t allow points to be moved
outside the active display area. Deselect this checkbox for increased flexibility.
