那是在2016年初，项目有需求，软件没这项功能，然后想到了自己做的MeGauging中有这样的功能，修改即可
谁也不知道
谁也没告诉
当时有点怕怕
很谨慎，反复测试，用了半年，很稳定，戒备心也慢慢放下了，就是下面这个图中红色的框，以及中心十字：
这个通道可以看得再清晰一些：
当下这个红色框占用的通道是20um宽度，一系列的还有8um通道，4um通道等等，激光就是要在这个晶圆通道切割。
代码如下：
double lmapsx1 = 0, lmapsy1 = 0, lmapex1 = 0, lmapey1 = 0;
ccbt.Calibration.GetComputedUncalibratedFromCalibratedTransform().MapPoint(startx, starty, out lmapsx1, out lmapsy1);
ccbt.Calibration.GetComputedUncalibratedFromCalibratedTransform().MapPoint(endx, endy, out lmapex1, out lmapey1);
//刻画通道矩形，用自己的代码，comefrom MeGauging
#region DrawRect
int tdwidth00 = Convert.ToInt32(tongdao00.Text);//这里是通道宽度
PointF m_RcCenter = drawtongdaorect(lmapsx1, lmapsy1, lmapex1, lmapey1, tdwidth00);
#endregion DrawRect
