Quick Question

[dud3]

I have the following code:

            var mousePos = _this.root.getPointer(e.e);
            mousePos.x = parseInt(mousePos.x);
            mousePos.y = parseInt(mousePos.y);
            var width = _this.root.getWidth();
            var height = _this.root.getHeight();
            var pixels = _this.root.getContext().getImageData(0, 0, width, height);
            var pixel = (mousePos.x + mousePos.y * pixels.width) * 4;
            _this.activePathsColor = new fabric['Color']('rgb(' + pixels.data[pixel] + ',' + pixels.data[pixel + 1] + ',' + pixels.data[pixel + 2] + ')');
            var colorHex = '#' + _this.activePathsColor.toHex().toLowerCase();

How would we use getImageDataFaster in this case.

Thanks.
