建立如图所示的作业：
在脚本中 public class UserScript : CogToolGroupBaseScript{ }内添加变量：
1 private double Distance = 0;
2 private CogDistancePointPointTool DistancePointPointToolObject;
在脚本GroupRun构造函数下添加代码：
1 DistancePointPointToolObject = (CogDistancePointPointTool) toolGroup.Tools["CogDistancePointPointTool1"];
2 Distance = DistancePointPointToolObject.Distance;
在脚本中ModifyLastRunRecord构造函数添加代码：
1 public override void ModifyLastRunRecord(Cognex.VisionPro.ICogRecord lastRecord)
2 {
3 CogGraphicLabel ResultLabel = new CogGraphicLabel();
4 string labelStr = string.Format("Distance={0:F2} pixel", Distance);
5 ResultLabel.SetXYText((DistancePointPointToolObject.StartX + DistancePointPointToolObject.EndX) / 2, DistancePointPointToolObject.EndY, labelStr);
6 ResultLabel.Color = Cognex.VisionPro.CogColorConstants.Green;
7 toolGroup.AddGraphicToRunRecord(ResultLabel, lastRecord, "图像转换_CogImageConvertTool1.OutputImage", "script");
8 }
完成代码如下：
1 using System;
2 using Cognex.VisionPro;
3 using Cognex.VisionPro3D;
4 using Cognex.VisionPro.ToolGroup;
5 using Cognex.VisionPro.Dimensioning;
