jtopo鹰眼的样式修改，(jtopo加鹰眼后，topo图中有一条连线的颜色被鹰眼边框颜色覆盖)

最近在写topo图的时候，topo图书莫名其妙出现一条黑色连线，但是数据库里并没有设计黑色的连线，经过反复确定发现只要显示鹰眼就会显示黑线，不显示鹰眼就不会显示那条黑线，效果如下图所示：

看代码是时候，在jtopo-0.4.8-min.js大概五百二十行左右有这样的代码，意识差不多就是鹰眼能看到的边框，灰色填充，以及拓扑显示，如果想简单粗暴的只改黑线的问题，把拓扑的边框影藏掉即可，既：代码中红色部分b.stroke()注释掉即可。

if (null != this.eagleImageDatas) {
    var b = a.graphics;
    b.save(),
        b.fillStyle = "rgba(211,211,211,0.3)",
        b.fillRect(a.canvas.width - this.canvas.width - 2 * this.hgap, a.canvas.height - this.canvas.height - 1, a.canvas.width - this.canvas.width, this.canvas.height + 1),
        b.fill(),
        b.save(),
        b.lineWidth = 1,
        b.strokeStyle = "rgba(0,0,0,1)",
        b.rect(a.canvas.width - this.canvas.width - 2 * this.hgap, a.canvas.height - this.canvas.height - 1, a.canvas.width - this.canvas.width, this.canvas.height + 1),
        b.stroke(),
        b.restore(),
        b.putImageData(this.eagleImageDatas, a.canvas.width - this.canvas.width - this.hgap, a.canvas.height - this.canvas.height),
        b.restore()
} else this.eagleImageDatas = this.getData(a)

我为了页面能稍微好看一点，对这段代码进行了修改，代码如下：

if (null != this.eagleImageDatas) {
    var b = a.graphics;
    b.save(),
        b.fillStyle = "rgba(0,0,0,0.5)",//鹰眼框左右两边填充颜色
        //fillRect绘制鹰眼显示topo节点的地方context.fillRect(x,y,width,height);x,y是矩形左上角的坐标，width和height是矩形的宽高---既鹰眼灰色矩形
        // console.log('x坐标',a.canvas.width - this.canvas.width - 2 * this.hgap);
        // console.log('y坐标', a.canvas.height - this.canvas.height - 2.5);
        // console.log('长',a.canvas.width - this.canvas.width);
        // console.log('宽',this.canvas.height + 3)
        b.fillRect(a.canvas.width - this.canvas.width - 1.3 * this.hgap, a.canvas.height - this.canvas.height - 2.5, 202, 163),
        // b.fill(),
        // b.save()
        // b.lineWidth = 1,//线条宽度
        // b.strokeStyle = "rgba(0,0,255,1)",//strokeStyle线条颜色
        // b.rect(a.canvas.width - this.canvas.width - 2 * this.hgap, a.canvas.height - this.canvas.height - 1, a.canvas.width - this.canvas.width-980, this.canvas.height -2)
        //b.stroke()
        b.restore(),
        b.putImageData(this.eagleImageDatas, a.canvas.width - this.canvas.width - 1.2* this.hgap, a.canvas.height - this.canvas.height - 1),
        b.restore()
} else this.eagleImageDatas = this.getData(a)

修改后的效果如下：

可以根据自己想要的效果进行微调，
