C#与Halcon联合编程

一、加载图片

导入并初始化

using HalconDotNet;
ho_Image = new HObject();

需要在引用中导入 halcondotnet.dll

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);

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);
