Chapter 20 Shapes, masks, and paint strokes 858
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: A checkbox that, when selected, maintains the defined width of the outline/
stroke when the shape is scaled. This option is available only when Solid is the selected
Brush Type.
•
Joint: A pop-up menu, available when Solid is the selected Brush Type, that sets how hard
corners on a shape’s outline are drawn. There are three options:
•
Square: All corners are squared off.
•
Round: All corners are rounded.
•
Bevel: All corners are cut at an angle.
•
Start Cap: A pop-up menu, available when Solid is the selected Brush Type, that lets you
choose the shape of an open outline’s start cap (the shape of the edge of an outline). There
are five options:
•
None: The stroke ends at the control point.
•
Square: The cap is squared off.
•
Round: The cap is rounded.
•
Bevel: The cap is cut at an angle.
•
Arrow: The cap is a customizable arrow. When Arrow is selected from the Start Cap or End
Cap pop-up menus, the Arrow Length and Arrow Width sliders appear.
•
End Cap: Pop-up menus that let you choose the shape of an outline’s end cap. This option is
only available when Solid is the selected Brush Type.
There are five options:
•
None: The stroke ends at the control point.
•
Square: The cap is squared off.
•
Round: The cap is rounded.
•
Bevel: The cap is cut at an angle.
•
Arrow: The cap is a customizable arrow. When Arrow is selected from the Start Cap or End
Cap pop-up menus, the Arrow Length and Arrow Width sliders appear.
•
Spacing: A slider, available when Airbrush or Image is the selected Brush Type, that defines the
space between dabs. A lower number creates a more solid line, and a higher number creates a
greater distance between dabs.
•
Additive Blend: A checkbox, available when Airbrush or Image is the selected Brush Type, that
composites all overlapping dabs together using the Additive blend mode. By default, dabs
are composited together using the Normal blend mode. The Additive blend mode occurs in
addition to whichever compositing method is already in use.
•
Reverse Stacking: A checkbox, available when Airbrush or Image is the selected Brush Type, that
inverts the order in which the dabs are stacked. To see the effect of this parameter, dabs must
be overlapping.
•
First Point Offset: A slider that lets you offset and animate the start point of the outline. This
is very useful for effects such as drawing a line across a map over time. (You can also use the
Shape Write On behaviors to draw a stroke or outline over time. For more information, see
Write On on page 881.)
•
Last Point Offset: A slider that lets you offset and animate the end point of the outline.
