前言

本章会简单讲解如何调用Halcon组件和接口，因为我们是进行混合开发模式。即核心脚本在平台调试，辅助脚本C#直接调用。

在MainWindow.xaml里面导入Halcon命名空间

<Window x:Class="Hello_Halcon.MainWindow"xmlns=""xmlns:x=""xmlns:d=""xmlns:mc=""xmlns:local="clr-namespace:Hello_Halcon"xmlns:halcon="clr-namespace:HalconDotNet;assembly=halcondotnet"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><Grid.RowDefinitions><RowDefinition Height="auto"/><RowDefinition /></Grid.RowDefinitions><!--添加Halcon图像导入事件--><Button Click="Button_Click" Content="加载图像"/><!--添加Halcon窗口--><halcon:HSmartWindowControlWPF Grid.Row="1" x:Name="hSmart"/></Grid>
</Window>

按钮事件

private void Button_Click(object sender, RoutedEventArgs e)
{//添加文件路径string fileName = "D:\\workspace\\program\\Halcon\\Images\\1.png\"";var image = new HImage(fileName);int width, height;image.GetImageSize(out width, out height);hSmart.HalconWindow.SetPart(0,0,width,height);hSmart.HalconWindow.DispObj(image);//自适应屏幕hSmart.SetFullImagePart();}

如果编译报错

安装System.Drawing.Common



如果出现上面问题记得看看有没有写hSmart.SetFullImagePart();

完美解决在我这篇文章中

Halcon WPF 开发学习笔记：HSmartWindowControlWPF正常加载

WPF简单调用Halcon

添加两个按钮

<Window.Resources><Style TargetType="Button" x:Key="MarginButton"><Setter Property="Margin" Value="3" /></Style>
</Window.Resources>
<Grid><Grid.RowDefinitions><RowDefinition Height="auto" /><RowDefinition /></Grid.RowDefinitions><!--添加Halcon图像导入事件--><StackPanel Orientation="Horizontal"><Button Click="Button_Click" Content="加载图像"Style="{StaticResource MarginButton}" /><Button Click="Button_Click_1" Content="创建圆形"Style="{StaticResource MarginButton}" /><Button Click="Button_Click_2" Content="创建矩形"Style="{StaticResource MarginButton}" /></StackPanel><!--添加Halcon窗口--><halcon:HSmartWindowControlWPF Grid.Row="1" x:Name="hSmart" />
</Grid>

添加按钮事件

 /// <summary>/// 画圆/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void Button_Click_1(object sender, RoutedEventArgs e){//创建一个圆形，圆心为(100,100)，半径为50var drawingObject = HDrawingObject.CreateDrawingObject(HDrawingObject.HDrawingObjectType.CIRCLE, new HTuple[] { 100, 100, 50 });//临时存放ListdrawingObjects.Add(drawingObject);//将圆画再hSmart画布上面hSmart.HalconWindow.AttachDrawingObjectToWindow(drawingObject);}

实现效果

这个圆是可以拖动的

创建矩形

和创建圆形一致，不再说明

private void Button_Click_2(object sender, RoutedEventArgs e)
{//创建一个矩形var drawingObject = HDrawingObject.CreateDrawingObject(HDrawingObject.HDrawingObjectType.RECTANGLE1, new HTuple[] { 100, 100, 150,250 });//临时存放ListdrawingObjects.Add(drawingObject);//将矩形再hSmart画布上面hSmart.HalconWindow.AttachDrawingObjectToWindow(drawingObject);
}
