The closePath() function
Summary: The closePath() function designates a path as closed and (possibly) draws a connecting line back to the start point
An example of the
closePath()
function
The closePath()
function is used to mark the path you're drawing as closed
so that you can begin another. It's important to remember
that this function doesn't always need to be used - the deciding factor can
be whether you want to draw a line back to the start
point for the current path. Sometimes this isn't applicable though - such as
when your path is only drawing a rectangle. In this
case the closePath()
might not be needed and you can just start a new path
with the beginPath()
function - and not call closePath()
.
In this case the closePath()
is implied by starting a new path
(but without drawing a connecting line to the start of the new path).
An example
<script>
window.onload = function ()
{
var canvas = document.getElementById("cvs");
var context = canvas.getContext('2d');
context.beginPath();
context.arc(100,100, 50, 0, Math.PI, false);
// This connects back to the start of the arc
context.closePath();
context.stroke();
}
</script>
