如何拉伸swf视频以适应C#中的播放器？

using System;
using System.Windows.Forms;

namespace VideoPlayer
{
    public partial class MainForm : Form
    {
        private AxShockwaveFlashObjects.AxShockwaveFlash swfPlayer;

        public MainForm()
        {
            InitializeComponent();
        }

        private void MainForm_Load(object sender, EventArgs e)
        {
            // 创建SWF播放器控件
            swfPlayer = new AxShockwaveFlashObjects.AxShockwaveFlash();
            swfPlayer.Dock = DockStyle.Fill;
            Controls.Add(swfPlayer);

            // 播放SWF视频
            swfPlayer.Movie = "video.swf";

            // 调整视频大小以适应播放器
            ResizeVideo();
        }

        private void MainForm_Resize(object sender, EventArgs e)
        {
            // 窗口大小改变时，重新调整视频大小
            ResizeVideo();
        }

        private void ResizeVideo()
        {
            // 获取视频的原始宽度和高度
            int videoWidth = swfPlayer.Width;
            int videoHeight = swfPlayer.Height;

            // 获取播放器的宽度和高度
            int playerWidth = ClientSize.Width;
            int playerHeight = ClientSize.Height;

            // 计算宽度和高度的比例因子
            double widthScale = (double)playerWidth / videoWidth;
            double heightScale = (double)playerHeight / videoHeight;

            // 取较小的比例因子作为最终的比例因子
            double scale = Math.Min(widthScale, heightScale);

            // 计算适应播放器的新宽度和新高度
            int newWidth = (int)(videoWidth * scale);
            int newHeight = (int)(videoHeight * scale);

            // 设置视频的显示区域
            swfPlayer.Width = newWidth;
            swfPlayer.Height = newHeight;
        }
    }
}
