The Pen property of a canvas controls the way lines appear, including lines drawn as the outlines of shapes. Drawing a straight line is really just changing a group of pixels that lie between two points.

The pen itself has four properties you can change:

- Color property changes the pen color.
- Width property changes the pen width.
- Style property changes the pen style.
- Mode property changes the pen mode.

The values of these properties determine how the pen changes the pixels in the line. By default, every pen starts out black, with a width of 1 pixel, a solid style, and a mode called copy that overwrites anything already on the canvas.

You can use TPenRecall for quick saving off and restoring the properties of pens.
