willReadFrequently on getResult() canvas ?

[Dylan190774]

In devtools console I get the following warning:

Canvas2D: Multiple readback operations using getImageData are faster with the willReadFrequently attribute set to true. See: https://html.spec.whatwg.org/multipage/canvas.html#concept-canvas-will-read-frequently

This happens when I use const result = this.$refs.cropper.getResult(); a few times after another and then do getImageData on the context of result.canvas

Any idea how to set willReadFrequently on the canvas of getResult ?

Found the solution, I just had to use :

const ctx = canvas.getContext('2d', { willReadFrequently: true });
when getting the context of the canvas.
