javascript - 如何从 Vibrant js 获取 LightMulated 颜色？

Question

我正在使用https://jariz.github.io/vibrant.js/为了从图像中获取颜色，他们在他们的网站上展示了示例，其中还显示了最白的颜色(LightMulated)，但是我可以获得任何其他值，但 LightMated 不会为我返回任何内容，我怎样才能获得该颜色？我尝试像这样使用它:

            albumart.addEventListener('load', function () {
                var vibrant = new Vibrant(albumart);
                var swatches = vibrant.swatches()
                for (var swatch in swatches)
                    if (swatches.hasOwnProperty(swatch) && swatches[swatch]) {
                    var name = (swatches.LightMuted.getHex()); // Nothing
                    var details = (swatches.DarkVibrant.getHex()); // Returns color

来自Vibrant.js

Note that some Swatches might be set to 'undefined' when Vibrant fails to find a matching color for the profile!

您可以先检查该值

var name = swatches.LightMuted ? swatches.LightMuted.getHex() 
                               : '#333' // default value
