Drawing with Paths
The list below is a refresher on drawing with paths:
1. Always start a new path with the
context.beginPath()
function call.
2. Set
context.strokeStyle()
before starting to draw the path.
3. Use a combination of the
context.moveTo()
and
context.drawTo()
stroke com-
mands to paint the path lines.
4. End the drawing with the
context.stroke()
call, and close off the path with
context.closePath()
.
