fabricjs - Fabric.js how to set opacity of lines -

-

using fabric.js library, can set line width , color follows:

canvas.freedrawingbrush.width = 5; canvas.freedrawingbrush.color = "#f00";

is there way set opacity too? couldn't find in documentation, neither on net anywhere.

instead of using hexadecimal color code, can set color use rgba, below:

canvas.freedrawingbrush.color = 'rgba(255, 0, 0, 0.1)';

demo jsfiddle
