如何删除滚动条

WPF + C# + Emgu CV UI有一个滚动条，我对其进行了设置

capture.SetCaptureProperty(Emgu.CV.CvEnum.CapProp.FrameHeight, 1024);

因为视频帧的高度和宽度大于UI的高度和宽度

private void OpenCv(ref  VideoCapture capture, int index = 0)
    {
        if (capture == null)
        {
            capture = new VideoCapture(index);
            if (capture.IsOpened)
            {
                capture.SetCaptureProperty(Emgu.CV.CvEnum.CapProp.Autofocus,0);
                capture.SetCaptureProperty(Emgu.CV.CvEnum.CapProp.FrameHeight, 1024);//设置捕捉到帧的高度为320  Width="246"  Height="210"
                capture.SetCaptureProperty(Emgu.CV.CvEnum.CapProp.FrameWidth, 1024);//设置捕捉到帧的宽度为240
                capture.FlipHorizontal = false;//捕捉到帧数据进行水平翻转
                capture.ImageGrabbed += eventHandler;
                capture.Start();
            }
            else
            {
                capture = null;
            }
        }
    }

Xaml

<wfi:WindowsFormsHost ScrollViewer.VerticalScrollBarVisibility="Hidden" 
                          HorizontalAlignment="Stretch"    >
    <emui:ImageBox   Enabled="False" 
                     AllowDrop="False"
                     AutoSize="True"

                     AutoScrollOffset="0,0"
                     x:Name="capturedImageBox" 
                     Paint="CapturedImageBoxPaint" />
</wfi:WindowsFormsHost>

如果尚未将WindowsFormsHost包裹在ScrollViewer中，则应将其包装在其标签内。

我的意思是

<ScrollViewer VerticalScrollBarVisibility="Hidden" ...>
 <wfi:WindowsFormsHost ...>
 //...
 </wfi:WindowsFormsHost>
</ScrollViewer>
