## Line

### Description

The Line object draws a single line, and is normally used for display purposes only. The `where` or `size` property is used to define the enclosing rectangle, with a special meaning. The first two parameters (top and left of the 'rectangle') are the starting position of the line. The second two (height and width of the 'rectangle') are the offset to the end of the line, and may be negative. For example, if `where` is 20 20 10 0, the line starts at 20 20 and is vertically downwards; if `where` is 20 20 ¯10 0, it is vertically upwards.

You can set the drawing (foreground) color using the `color` property, and the `pensize` property changes the thickness of the lines.

Note: Remember that the default scale is in character units. See the `scale` property for details.

See also the Draw method which allows you to draw geometric shapes on your windows and controls.
