Constraining, fading, and undoing strokes

---

Using the freehand stroke drawing style, you can constrain your strokes to a straight line. The angle you draw depends on the orientation of the stroke.

You can also make a stroke less opaque, or more translucent, by fading the stroke.

In this example, a brushstroke was applied to the canvas (left) and then fade was applied to the brushstroke (right) by using the Fade dialog box (center).

In addition, you can undo a stroke. You can also control how many individual strokes can be undone, see Performance preferences.
