Join Joe Marini for an in-depth discussion in this video Lines, part of Learning HTML Canvas.
- [Instructor] Now that we've seen how to draw rectangles…let's learn about how to draw lines.…There are a variety of functions and settings…for drawing lines.…The first two functions moveTo and lineTo…are used to perform operations on the drawing pen.…So you can imagine there's this invisible pen…that can move around the canvas and draw lines.…The moveTo function positions the pen…but does not perform any actual drawing,…whereas the lineTo function will draw a line…using the current line settings.…The next three properties, lineWidth, lineCap, and lineJoin…determine how the line is drawn.…
So we've already seen the lineWidth property,…and that determines how wide the line is.…The lineCap property defines how the ending of a line…is drawn and there's three settings for that property…and we'll see examples of these.…The lineJoin property determines how you join lines together…when you do multiple lineTo operations…and this can be a round, bevel,…or what's called a miter join, which is the default.…And we'll see examples of these.…
