The lineJoin
property is used to set how lines are drawn when they are
connected. There are three possible values: bevel
round
and miter
. Initially, the setting is miter
. Below are examples of the
different types.
An example
<script> window.onload = function () { var canvas = document.getElementById("cvs"); var context = canvas.getContext('2d'); // Translate by half a pixel - this makes lines look crisp context.translate(0.5, 0.5); context.beginPath(); context.lineJoin = 'bevel'; context.lineWidth = 25; context.moveTo(50,150); context.lineTo(100,50); context.lineTo(150, 150); context.stroke(); } </script>
