•
Order: A pop-up menu that sets whether an outline is drawn over or under the shape fill color
or gradient. The effect is more apparent with thicker outline widths. There are two menu items:
•
Over Fill: Outlines appear on top of the selected fill of the shape.
•
Under FIll: Outlines are obscured beneath the selected fill of the shape.
Style pane movie controls
Additional controls appear in the Style pane when the Brush Source is a multi-frame object such
as a QuickTime movie or image sequence.
Movie parameters in the Style pane
•
Play Frames: A checkbox that controls playback of Brush Source movie or image sequence. If
the checkbox is selected, playback of the clip loops. If the Play Frames checkbox is deselected,
the paint dabs use the still frame specified by the Random Start Frame parameter or the
Source Start Frame parameter.
•
Random Start Frame: A checkbox that introduces variation to image brush strokes when the
Brush Source parameter contains a multi-frame movie or image sequence. If the checkbox
is selected, each dab will pull from a random frame in the source clip. The dab will start
animating from this random frame or remain still, depending on whether the Play Frames
checkbox is selected or deselected. This pattern of randomness can be adjusted by using the
Random Seed button in the Stroke pane.
•
Source Start Frame: A mini-curve editor that defines the frame where playback of the source
clip begins in the paint dabs. (For information on using the mini-curve editor, see
Mini-curve
editor on page 482.) The Source Start Frame default keyframe value is 0. You can change the
start frame for all dabs, or you can create a curve so start frames vary over the length of the
stroke (different dabs use different start frames). For example, if the first Source Start Frame
value is 50, each dab begins playback at frame 50. If you create an animation curve that begins
at 50 and ends at 250, each dab begins clip playback at a progressively later frame.
Note: The Play Frames checkbox must be selected for playback to occur. If Play Frames is
deselected, you can display different still frames over the length of the stroke. This parameter
only appears if Random Start Frame is deselected.
When you click the Source Start Frame disclosure triangle, the Stroke Length and Source Start
Frame subparameters become available:
•
Source Start Frame Over Stoke: A slider that adjusts the value of the selected keyframe in the
mini-curve editor.
•
Stroke Length: A slider that adjusts the value of the selected keyframe. Stroke Length is
mapped horizontally on the mini-curve editor graph and provides a visual representation of
the position of the changes in start frame value (keyframes) over the length of the stroke.
•
Hold Frames: A slider that sets the number of times each frame of the source movie is repeated
during playback. The larger the Hold Frames value, the slower your playback.
•
Hold Frames Randomness: A slider that varies the number of frames to “hold.”
