VisionPro · C# · 界面显示视觉结果图像

程序界面通过 CogRecordDisplay 控件显示视觉运行结果图像。

按指定图像显示，代码如下：

using System;
using System.Windows.Forms;
using Cognex.VisionPro;
using Cognex.VisionPro.ToolBlock;

        /// <summary>
        /// 显示指定视觉图像
        /// </summary>
        /// <param name="cogdisplay">显示控件</param>
        /// <param name="cogImage">显示图像</param>
        public void ShowDisplayByImage(CogRecordDisplay cogDisplay, CogImage8Grey cogImage)
        {
            try
            {
                cogDisplay.Image = null;
                cogDisplay.StaticGraphics.Clear();
                cogDisplay.InteractiveGraphics.Clear();
                cogDisplay.Image = cogImage;
                cogDisplay.AutoFit = true;
            }
            catch (Exception ex)
            {
                MessageBox.Show("图像显示失败！");
            }

        }

按指定VisionPro 工具包 CogToolBlock 内的工具序号显示该工具结果图像，代码如下：

using System;
using System.Windows.Forms;
using System.IO;
using Cognex.VisionPro;
using Cognex.VisionPro.ToolBlock;

        /// <summary>
        /// 显示工具图像
        /// </summary>
        /// <param name="CogTB">显示工具文件</param>
        /// <param name="cogdisplay">显示控件名称</param>
        /// <param name="ShowSubRecordsIndex">视觉工具序号</param>
        public void ShowDisplayByTool(CogRecordDisplay cogDisplay, CogToolBlock CogTB, int ShowSubRecordsIndex)
        {
            try
            {
                cogDisplay.Image = null;
                cogDisplay.StaticGraphics.Clear();
                cogDisplay.InteractiveGraphics.Clear();
                if (CogTB != null)
                {
                    cogDisplay.Record = CogTB.CreateLastRunRecord().SubRecords[ShowSubRecordsIndex];//按序指定工具图像
                    //cogdisplay.Record = CogTB.CreateLastRunRecord();//最后一张
                    cogDisplay.AutoFit = true;
                    cogDisplay.Fit();
                }
                else
                {
                    MessageBox.Show("显示工具文件不存在！");
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("图像显示失败！");
            }

        }
