draw a straight horizontal line

BobArning: There are several methods that will help here. See:

`   FormCanvas>>line:to:width:color: `

Dan Ingalls: For a line object, use PolygonMorph in its PolyLine mode, thus

```World addMorph:
(PolygonMorph
vertices: {pointA. pointB}
color: Color red
borderWidth: 2
borderColor: Color red)```

You want to do draw some free flowing shapes. Get a Canvas so that you can draw on a Form. Use drawBezierShape: to draw one or more Bezier line segments.

In the following example, we draw a shape that looks vaguely like the Nike logo with the top cut of. First, we get a balloon canvas so we can draw on the Display (as opposed to the form of a Morph.) We draw two rounded line segments and one straight line segment. Each segment is defined by three points: begin-, mid- and end-point. A straight line is created by setting the mid-point equal to the end-point (or the begin-point, it doesn’t matter.) Since, the three line shapes in our example, make a continuous line we get a red filled “swoosh” outlined in red. (Note: the seldom used braces {} used to define the array of points.)

```Display getCanvas asBalloonCanvas aaLevel: 4;
drawBezierShape: {30 @ 30. 30 @ 200. 200 @ 10.
200 @ 10. 50 @ 150.  50 @ 30.
50 @ 30. 30 @ 30.   30 @ 30}
color: Color red
borderWidth: 1
borderColor: Color green```
