Question

我看过这个article，我想知道我是否可以用图像列表替换画笔？

这是从brush创建AVI文件的代码：

        private void buttonCreateVideo_Click(object sender, EventArgs e)
    {
        int width = 640;
        int height = 480;

        VideoFileWriter writer = new VideoFileWriter();
        writer.Open("code-bude_test_video.avi", width, height, 25, VideoCodec.MPEG4, 100000);

        Bitmap image = new Bitmap(width, height);
        Graphics g = Graphics.FromImage(image);
        g.FillRectangle(Brushes.Black, 0, 0, width, height);
        Brush[] brushList = new Brush[] { Brushes.Green, Brushes.Red, Brushes.Yellow, Brushes.Pink, Brushes.LimeGreen };

        for (int i = 0; i < listBox1.Items.Count; i++)
        {
            Application.DoEvents();
            g.FillRectangle(brushList[i % 5], (i % width) * 2, (i % height) * 0.5f, i % 30, i % 30);
            g.FillRectangle(brushList[i % 5], (i % width) * 2, (i % height) * 2, i % 30, i % 30);
            g.FillRectangle(brushList[i % 5], (i % width) * 0.5f, (i % height) * 2, i % 30, i % 30);
            g.Save();
            writer.WriteVideoFrame(image);
        }

        writer.Close();
    }

这是我的清单：

private void button2_Click(object sender, EventArgs e)
{
    FolderBrowserDialog fbd = new FolderBrowserDialog();
    DialogResult result = fbd.ShowDialog();

    if (result == DialogResult.OK)
    {
        NumericComparer ns = new NumericComparer();
        string[] array1 = Directory.GetFiles(fbd.SelectedPath, "*.Jpeg");
        ns = new NumericComparer(); // new object
        Array.Sort(array1, ns);

        listBox1.Items.Clear();
        foreach (string name in array1)
        {
            listBox1.Items.Add(name);
        }
    }
}

我只需要从文件夹中添加图片并将其保存在.avi视频

中

我认为是这样的：

for(int i = 0; i < listBox1.Items.Count; i++)
{
    Application.DoEvents();
    var frame = new Bitmap(name);
    g.DrawImage(frame, 0, 0, width, height);
    writer.WriteVideoFrame(image);
}

用图像列表替换画笔？
