Question

我正在尝试选择一个图像并将其拆分为9个并随机放置在画布中。我正处于选择图像的位置，但我不确定如何分割图像。我看过类似的问题，但没有运气。我不是在寻找其他人来做这项工作，而是建议如何做到最好。

private void uploadImage_Click(object sender, RoutedEventArgs e)
{
    //creates (but not yet displays) a OpenFile dialog box
    Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

    //specifies the look of the open file dialog box
    dlg.DefaultExt = ".jpg";
    dlg.Filter = "Image Files|*.jpg;";
    dlg.InitialDirectory = Environment.CurrentDirectory;

    //shows the open file dialog box to user and awaits OK or Cancel
    bool? result = dlg.ShowDialog();

    //result is true if user selects an image file
    if (result == true)
    { 
        filename = dlg.FileName;
        var uri = new Uri(filename);
        var bitmap = new BitmapImage(uri);
        Image bg = new Image();

        bg.Source = new BitmapImage(uri);
    }
    else
        return;
}
