•
Scroll Rate Mult: Use this slider, available when Speed Control is set to Automatic, to multiply
the rate of the scroll. Amounts higher than those available in the slider can be entered in the
value slider (the number field at the right of the slider).
•
Scroll Rate: Use this slider, available when Speed Control is set to Fixed, to set the speed of the
scroll in pixels per second.
•
Reduce Flicker: Use this pop-up menu to modify the speed of the scroll to reduce flickering on
interlaced or progressive displays. When Scroll Direction is set to Vertical and Speed Control
is set to Automatic or Custom, the options are None, Progressive, or Interlaced. When Scroll
Direction is set to Horizontal and Speed Control is set to Automatic or Custom, the options are
No or Yes.
•
None: Available when Scroll Direction is set to Vertical, this option has no effect on the speed
of the scroll.
•
Progressive: Available when Scroll Direction is set to Vertical, this option prevents flicker on a
progressive display (such as an LCD television). The Progressive setting is not guaranteed to
prevent flicker on an interlaced display (such as a CRT television).
•
Interlaced: Available when Scroll Direction is set to Vertical, this option prevents flicker on
a progressive display (such as an LCD television) or on an interlaced display (such as a CRT
television).
Note: Because the minimum speed to prevent flicker on an interlaced display is 2 pixels per
frame, and the minimum speed to prevent flicker on a progressive display is 1 pixel per frame,
the Interlaced option may result in faster scroll rates.
•
No: Available when Scroll Direction is set to Horizontal, this option does not modify the scroll
speed to reduce flickering on interlaced or progressive displays.
•
Yes: Available when Scroll Direction is set to Horizontal, this option modifies the speed of the
scroll to reduce flickering on interlaced or progressive displays.
•
Allow Layout Override: Select this checkbox, to permit manual changes to text layout. For
example, when horizontally scrolling imported RTF text, the text is placed in a single line. If the
Allow Layout Override checkbox is selected, the text retains its paragraph form.
Note: This parameter is available only when the Scroll Text behavior is applied to a text object.
•
Start Off-Screen: Select this checkbox to move the text to an off-Canvas position for the start of
the scroll.
