Depending on the Airbrush variant, you can reverse the effect of moving the
airbrush fingerwheel by enabling the Invert check box on the Color
Expression palette, or by enabling the Invert Flow Expression check box on
the Stroke Designer page of the Brush Creator.
In the Brush Creator, you can also determine flow based on stylus
information, such as velocity or pressure, by choosing an expression from the
Flow Expression pop-up menu.
Recording and Playing Back Strokes
Corel Painter will play back any stroke you record, wherever you click in the document
window. In this way, you can easily create a series of identical strokes — for example,
when you create hatching effects.
A brush stroke (top) is recorded and played back within a triangular selection.
Another way to use a recorded stroke is with Auto Playback, which lets you repeat the
recorded stroke at random positions on the page.
You can also save recorded strokes for later use. You can play back saved strokes, and
you can paint with the data from a saved stroke. This way of working can be
particularly useful if you work sometimes with a stylus and sometimes with a mouse:
you can record the brush strokes you make with a stylus, save them for later use, and
then use a mouse to obtain the data from that stroke, allowing stylus-quality results.
Corel Painter has a number of brush stroke scripts that can be played back on their
own or used in conjunction with an original brush stroke. When you use a brush stroke
script, your freehand brush strokes adhere to the stroke data in the script. This allows
you to emulate features of a tablet and stylus while using a mouse.
