Pattern
Size and Border Width, Softness, and Symmetry
■ Patterns can have a matte-filled border if you turn on the
[BORDER]
pushbutton. When [BORDER] is on, the (WIDTH) knob
sets the width of the border. The Matte controls set the edge
color.
■ When you turn on the [SOFT] button, the (SOFTNESS) knob sets
the diffusion of the pattern edge. When the [SOFT] button is
off, the pattern has a hard edge.
■ If the [SYMM] and [SOFT] buttons are both on, the (SYMMETRY)
knob sets the balance or evenness of the softness applied to
the pattern edge. When the [SYMM] button is off, softness of the
edge is evenly balanced. When the [SOFT] button is off, the
symmetry control has no effect.
Mask/Preset Invert
When you select a mask or preset pattern, you can toggle the
[MASK/PRESET INVERT]
button to change the area of the picture that
is affected by the mask or fill video. When the invert function is
off, the white area on the pattern buttons represents the area of the
screen where masking occurs or where the fill video appears.
When the invert function is on, the black area on the pattern
buttons represents the area of the screen where masking occurs or
where the fill video appears.
Wipe Menu
When you press the [MENU] button, the Wipe menu appears in the
menu display. This menu provides access to additional wipe
patterns as well as additional pattern modifiers, including aspect
ratio adjustments, sine wave modulation of the pattern, pattern
rotation, and pattern multiplication.
