function InfoImage(path,title){
    this.path = path;
    this.title = title;
    this.color = undefined;
    this.maxPixels = undefined;

    this.init = function(){
        var canvas = document.querySelector("canvas");
        var img_Color = new Image_Processing_Color(canvas);
        var img = new Image();
        img.onload = function () {
            img_Color.init(img);
            this.color = img_Color.getDominantColor(); //this doesnt work
            this.maxPixels = img_Color.getDominantColorPixels();
        };
        img.src = path;
    };


    this.init();
}

在这个例子中，我如何将这些变量保存为 InfoImage 变量？我知道在this那里使用会影响 Image 而不是 InfoImage ...
