贡献一个小程序，用于辅助页面设计的，喜欢的来顶下
正常情况下，我们的页面中链接是这样的
<a href = "http://blog.csdn.net/prsniper" target="_blank">虎胆游侠</a>
这样，我们点击“虎胆游侠”就会弹出一个新窗口，然后打开我的主页……
然而，这样的a标签只能用一个矩形把文字区域框住，十分单调。
在一些特殊的情况下，我们需要不规则的链接，比如艺术化的导航菜单，不规则按钮，地图……等等。
给a标签内嵌套img并不能完全满足，这些需求。
一个可行的做法是用img做map，相信很多人都会，usemap=“#map”就可以使用area做特殊形状的链接了，
包括rect矩形，circle圆形，polygon（DW自动完成是poly）。
rect还有什么用？ 它的意义是用一张图片的不同区域做不同的链接……
最强大的是polygon，其实熟悉WindowsAPI的程序员，VB,VC或Delphi等都知道有几个多边形绘图函数，这里我就不说了。
其模型基本一致，只要给出一系列的坐标即可。我这个程序就是方便大家计算出这一些列的坐标。
VB版源码及编译好的程序我会稍后上传到我的资源。
现在展示一个小demo吧！

用到下面的图片，保存为 guangxi.gif
打开页面，鼠标经过每个广西的城市都自动框选轮廓并显示名称……
效果如图：
工具的使用方法，因为只是个小工具，简单制作了。时间也是问题。
不过，麻雀虽小，五脏俱全：在文件路径栏输入文件路径，点“读”导入图片，支持bmp，jpg和gif
可以选择缩放，拖动查看局部，鼠标经过要选的点后按空格（需要先激活图片，也就是让图片获得焦点）
现在只能把得到的坐标显示到文本框中，也足够了
有不明白的地方或者任何建议，再联系我吧！
本来想直接上程序，但是怕怕CSDN文章中不能使用脚本
打击的话就先别来了，最近身体不太舒服，心情差。
