根据客户要求，每次视觉取像运行完毕后，按需保存OK或NG图像，图像分两种：

1.带视觉工具运行结果图像；

2.相机取像原图，.bmp格式。

保存图像代码如下：

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

        /// <summary>
        /// 保存图像
        /// </summary>
        /// <param name="image">需要保存的图片</param>
        /// <param name="imageNmane">图像保存名称</param>
        /// <param name="imagePath">图片保存路径</param>
        public void SaveImage(ICogImage image, string imageNmane, string imagePath)
        {
            CogImageFile mImageFile = new CogImageFile();
            string path = "";
            imagePath = System.IO.Directory.GetCurrentDirectory() + "\\VisionRecord\\Image\\" + DateTime.Now.ToString("yyyy-MM-dd") + "\\" + imagePath;
            if (!Directory.Exists(imagePath))
            {
                Directory.CreateDirectory(imagePath);
            }
            try
            {
                if (imageNmane != "")
                {
                    path = imagePath + "\\" + imageNmane + ".bmp";
                }
                else
                {
                    path = imagePath + "\\" + DateTime.Now.ToString("HHmmss") + ".bmp";
                }
                mImageFile.Open(path, CogImageFileModeConstants.Write);
                mImageFile.Append(image);
                mImageFile.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show("图像保存失败！");
            }
        }
