CanvasRenderingContext2D.direction

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.

Syntax

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

Options

Possible values:

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

The default value is "inherit".

Examples
