The line width is set using the
lineWidth
property. Just
give it a width, like this:
lineWidth = 5
- you get
a line width of 5px
. Let's
look at an example:
<canvas width="200" height="200" style="background: #f4f4f4;"></canvas>
let canvas = document.querySelector('canvas');
let ctx = canvas.getContext('2d');
ctx.beginPath();
ctx.lineWidth = 5; // width of 5px
ctx.moveTo(50, 50);
ctx.lineTo(150, 50);
ctx.stroke();
:
A width can also be changed for outlines,
such as those drawn with rect
:
<canvas width="200" height="200" style="background: #f4f4f4;"></canvas>
let canvas = document.querySelector('canvas');
let ctx = canvas.getContext('2d');
ctx.rect(50, 50, 100, 100);
ctx.lineWidth = 5;
ctx.stroke();
