Join Joe Marini for an in-depth discussion in this video Arcs, part of Learning HTML Canvas.
- [Instructor] Up until now we've seen how…to draw simple shapes like rectangles and lines.…In this example we'll take a look at drawing…some more complex shapes, starting with arcs and paths.…So what is a path?…A path is basically a sett of connected points,…and the points are connected by lines or by curves,…and a path is either open or closed.…The current drawing context always has one,…and only one, current drawing path.…So a closed path has an endpoint…that is the same as the starting point.…Or, the canvas can automatically draw a line…from the ending point to the starting point…and close the path for you.…
To begin creating a path, you use the beginPath() method.…To add segments to the path,…you basically use one or more path-drawing routines.…To stroke the current path, you use the stroke() function…and to fill it, you call fill().…To close the current path, should you decide to close it,…you would call closePath()…and in the case the endpoint is not the same…as the start point, the canvas will close the path for you.…
