openSeadragon怎么展示本地图片？

Question

openSeadragon 怎么打开2.kfb这个图片， tileSources:'/images/2.kfb'+'.dzi',，现在这么写是错的，当前文件结构是这样的

                this.viewer = OpenSeadragon({
                    element: this.$refs.openSeadragonElement,
                    **tileSources:'/images/2.kfb'+'.dzi',**
                    /**
                     * 控制按钮
                     */
                    zoomInButton: 'zoom-in',
                    zoomOutButton: 'zoom-out',
                    homeButton: 'go-home',
                    fullPageButton: 'full-screen',
                    toolbar: 'toolbar',

                    /**
                     * 鼠标控制
                     */
                    gestureSettingsMouse: {
                        scrollToZoom: true,
                        clickToZoom: false,
                        dblClickToZoom: false
                    }
                });
