Question

我正在尝试保存使用网络摄像头捕获的图片框图像。我正在使用AForget.NET。

我想做的是，当我单击“确定”按钮并获取已保存到文件夹的路径时，我希望将该图片框图像保存到“项目/特定文件夹”中。

我收到GDI +错误

这是我的代码

RegisterCustomer _regCustomer;

    public UpdateImageCapture(RegisterCustomer regCustomer)
    {
        InitializeComponent();
        _regCustomer = regCustomer;
    }

    ImageHelper img = new ImageHelper();

    private void ImageCapture_Load(object sender, EventArgs e)
    {

        img.ImageSettings
        (
            img._captureDevice,
            img.finalFrame,
            cboxWebcamType
        );

        img.finalFrame.NewFrame += new NewFrameEventHandler(FinalFrame_NewFrame);

        btnOk.Hide();
        btnCancel.Hide();
    }

private void FinalFrame_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
        picPreviewImage.Image = (Bitmap)eventArgs.Frame.Clone();
}

这些代码指定当单击按钮捕获时，picCaptureImage（Picturebox2）将获得picPreviewImage（Picturebox1）的克隆副本

注意：Picturebox1通过摄像头显示自己的身影

private void BtnCapture_Click(object sender, EventArgs e)
{
        picCapturedImage.Image = (Bitmap)picPreviewImage.Image.Clone();
        picCapturedImage.BringToFront();
        btnCapture.Hide();
        btnOk.Show();
        btnCancel.Show();
}

private void BtnOk_Click(object sender, EventArgs e)
{
   if (picCapturedImage.Image != null)
        {
            var bitmap = new Bitmap(picCapturedImage.Image);
            var newBitmap = new Bitmap(bitmap);
            bitmap.Save(@"C:\Users\dieth\source\repos\SalesInventorySystem\SalesInventorySystem\Resources", ImageFormat.Png);
            bitmap.Dispose();
            bitmap = null;
        }
        else {
            MessageBox.Show("NULL");
        }
}

我解决了它，但是当我尝试再次捕获图像时，它只是替换了该文件中的图像。

sys.setdefaultencoding('utf-8') #added since it would give error for certain values when using str(i)

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
prefs = {'profile.managed_default_content_settings.images':2}
chrome_options.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(chrome_options=chrome_options) 

maxcr = 1379
