2. vs implementation
2.1 Interface Settings
Add corresponding controls according to requirements. In this case, panel is used to implement image display.
2.2 Preparation work-setting panel control object
It can be understood as: the pointer/interface that controls the image window
Note the statement that generates the image control in the periphery: private HSmartWindowControl hsWControl;
private void Form1_Load(object sender, EventArgs e)
{
//Create an image control object and add it to the panel container by filling it.
hsWControl = new HSmartWindowControl();
hsWControl.Dock = DockStyle.Fill;
panel1.Controls.Add(hsWControl);
}
2.3 Implement the image loading function
Note the declaration of the peripheral generated image variable private HImage ho_imge;
private void button1_Click_1(object sender, EventArgs e)
{
//Use the file dialog class OpenFileDialog to specify filter files
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "Select template image|*.png";
if(ofd.ShowDialog()==DialogResult.OK )
{
//Get the path, create an image through the path, display it, and set the image to adapt to the container size (proportional scaling without distortion)
string filePath = ofd.FileName;
ho_imge = new HImage(filePath);
hsWControl.HalconWindow.DispObj(ho_imge);
hsWControl.SetFullImagePart();
}
}
Extra +
OpenfileDialog: function class, which can pop up a file dialog box.
- Title: Set the title text of the dialog box.
- Multiselect:Set whether to allow multiple file selections. The default value is false. If set to true, you can hold down the Ctrl or Shift key while selecting multiple files.
- Filter:Set the file types that can be selected. The format is “Description text | File type”. Multiple types are separated by vertical bars |. If not set, all files can be selected by default.
- ShowDialog(): Display the dialog box for opening the file and return the dialog box results. The dialog result is true if the user selects the file and false if the user deselects it.
- FileNames: Gets the file name selected by the user. If the Multiselect property is true, a string array is returned; otherwise, a string array of length 1 is returned.
- FileName: Gets the first file name selected by the user, equivalent to FileNames[0].
Implement multiple file traversal and use container storage.
List<string> imageListPath· = GetOpenFilesPath("Select image file", true, "PNG file(*.png)|*.png|JPG file(*.jpg)|*.jpg)|BMP file(* .bmp");
