Pen Tool

The pen tool allows you to draw on the screen and produce one of several different pen strokes. The box at the bottom of the panel shows you the shape and name of each style of stroke that's available. The current Stroke Color will be the color of the drawn path.

The Brush Size option allows you to specify how wide of a stroke is drawn.

The Smoothing option allows you to control how much automatic smoothing is applied to any paths drawn. Maximum smoothing will remove many points in an attempt to make a very smooth curve (at the expense of accuracy). Minimum smoothing will leave all points in the path, preserving accuracy (what you draw is what you get).

Elements drawn with the Pen tool can be filled with either a solid color or a gradient. You can also apply a drop shadow to pen elements, as well as bevel/emboss them.

The widget for pen elements also allows you to modify the shape of the stroke after you have completed it.
