需要什么改进

myfreemind 发表于 2003-4-18 21:20:00

怎么说呢，其实我就是想让网友用我的程序，然后发现哪里有问题，可以互相探讨！

我经常和图形打交道，为了把图形做的美观一点，所以不太满意CAD中的一些功能，总想自己做程序来改进，比如我写的那个坐标注记程序，X，Y坐标中间的分隔线在不同的比例尺下是不同长短的，因为我不知道文本的屏幕距离怎么获得，所以就用笨办法每个比例尺都取取一个值，做到分隔线和文本长度一样，这样才比较美观~~~

Re: 文字的距离

单行的文字可以用GetBoundingBox来获取，但是文字必须是水平的，并且不能使用ScaleFactor设置了缩放。
而多行的文字要用到组码来获取，可以参考其它资料。
