Wipe Subpanel
Turning the SYMMETRY knob controls the relative softness
between the inside and outside wipe border edges, when the
SOFT
and BORD buttons are turned on. The last value of
SYMMETRY is remembered when either BORD or SOFT is turned
off.
BORD toggles control of the wipe border on and off. When BORD
is on, the adjacent WIDTH and OPACITY knobs become active for
modifying the wipe border. The wipe border is functional on
transition and preset wipes only.
The WIDTH knob sets the width of the wipe border when BORD is
on. When BORD is turned off, the last value of WIDTH is
remembered and is recalled when BORD is turned on again.
The OPACITY knob controls the opacity or translucence of the
wipe border when BORD is on. The OPACITY value is remembered
when BORD is turned off.
PRESET SIZE adjusts the wipe pattern size for preset patterns used
in non-transitional wipe patterns. It is also used to adjust the size
of masks that use the wipe generator.
The ASPCT button toggles control of the ASPECT knob (horizontal
to vertical ratio) of the wipe pattern on and off.
Turning the ASPECT knob clockwise from mid-position stretches
the horizontal axis of the wipe pattern. Similarly, turning the knob
counter-clockwise from mid-position stretches the vertical axis.
