This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The CanvasRenderingContext2D.direction property of the Canvas 2D API specifies the current text direction used when drawing text.


ctx.direction = "ltr" || "rtl" || "inherit";


Possible values:

The text direction is left-to-right.
The text direction is right-to-left.
The text direction is inherited from the <canvas> element or the Document as appropriate.

The default value is inherit.


Using the direction property

This is just a simple code snippet using the direction property to set a different text baseline setting.


<canvas id="canvas"></canvas>


var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

ctx.font = '48px serif';
ctx.direction = 'ltr';
ctx.strokeText('Hello world', 0, 100);

Edit the code below and see your changes update live in the canvas:
