I have a text that needs to have two gradient strokes. Can't find information oh how to achieve this:
P.S. I can't place different size text on top of each other, need to work only with one.
I've submitted a PR to PIXI which gives you some of your required functionality; you are now able to set gradients on the stroke, just as you can with fill.
Check out https://github.com/pixijs/pixi.js/pull/4016 for to track its progress and for examples.
However, your double stroke cannot be added in at library level, text in PIXI uses the canvas api (https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Drawing_text) and that only supports a single stroke.
