javascript - fabric.js - 创建对象后更改画笔描边颜色

Question

您可以从 Canvas 中获取事件对象并更改其属性，例如填充，描边。是否可以获得免费绘制的笔触并更改其颜色？

这是我正在运行的函数:

function dtUpdateColor(color) {
    let c = color;
    let o = canvas.getActiveObject();

    // If a group selection, do nothing
    if (canvas.getActiveGroup()) {
            canvas.deactivateAll().renderAll();
    } else {
        // If single object selected
        if ( c && o ) {
            // Works for shapes, not brush
            canvas.getActiveObject().fill = c;
            // Doesn't work
            canvas.getActiveObject().color = c;
            canvas.renderAll();
        }
    }
}
