When a movie or image sequence is the brush source, additional parameters appear.
For more about Movie or image sequence parameters, see
Brush Source Is a QuickTime Movie or Image Sequence
.
• Brush Profile: Available when Airbrush is the selected Brush Type, this gradient editor
allows you to create varying levels of opacity within the brush. The brush profile uses
the same opacity controls as a standard gradient editor. For more information, see
The default gradient
creates a soft airbrush.
Modify the Brush Profile opacity gradient to create new brush looks.
• Width: A slider that changes the width of a shape’s outline or width of a paint stroke’s
dabs. On paint strokes, width adjustments will alter the size of the dab while also
maintaining the spacing between each dab.
Note: If you used the pressure parameters in the Paint Stroke Tool HUD to create
variations in the stroke when the stroke was created, adjusting the Width parameter
affects the width of the stroke uniformly.
• Preserve Width: When this checkbox is selected, the defined width of the outline/stroke
does not change when the shape is scaled. This option is only available when Solid is
the selected Brush Type.
