一、加载图片

1. 导入并初始化

using HalconDotNet;
ho_Image = new HObject();

需要在引用中导入 halcondotnet.dll

2. 关联句柄 打开新窗口

//创建一个句柄变量 绑定winform 窗口  
HTuple winfowFater = this.pictureBox1.Handle;
//打开新的窗口
HOperatorSet.SetWindowAttr("background_color", "green");
HOperatorSet.OpenWindow(0, 0, this.pictureBox1.Width, this.pictureBox1.Height, winfowFater, "", "", out windowId);
HDevWindowStack.Push(windowId);

3. 加载图片

//读取图片
HOperatorSet.ReadImage(out ho_Image, "1.bmp");
//获取图片大小
//定义宽和高德变量 
HTuple hv_Width = new HTuple(), hv_Height = new HTuple();
HOperatorSet.GetImageSize(ho_Image, out hv_Width, out hv_Height);
//自适应
HOperatorSet.SetPart(windowId,0,0, hv_Height, hv_Width);
//在窗口显示图片
HOperatorSet.DispObj(ho_Image, windowId);

4. 完整代码

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
