lineWidth property
The lineWidth property sets
the line width when drawing on the
canvas.
Syntax
context.lineWidth = integer;
Example
Let's draw a line and set its
width to 5 pixels:
<canvas id="canvas" width="200" height="200" style="background: #f4f4f4;"></canvas>
let canvas = document.querySelector('#canvas');
let ctx = canvas.getContext('2d');
ctx.beginPath();
ctx.lineWidth = 5; // 5px width
ctx.moveTo(50, 50);
ctx.lineTo(150, 50);
ctx.stroke();
:
Example
Width can also be changed for strokes,
such as those drawn with
rect:
<canvas id="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();
