Answer 1

javascript 如何把网页(html)转成图片文件
不可能，javascript功能没这么强加。用C#将html字符串生成网页后转化为图片。
这应该行的通，好像WinForm里有个WebBrower控件，用那个控件呈现html，然后截屏。

        public Form1()
        {
            InitializeComponent();
            this.webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
        }        void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            GetImage();
        }        void GetImage()
        {
            if (webBrowser1.Document == null) return;
            try
            {
                int scrollHeight = webBrowser1.Document.Body.ScrollRectangle.Height;
                int scrollWidth = webBrowser1.Document.Body.ScrollRectangle.Width;
                webBrowser1.Size = new Size(scrollWidth, scrollHeight);
                Bitmap bm = new Bitmap(scrollWidth, scrollHeight);
                webBrowser1.DrawToBitmap(bm, new Rectangle(0, 0, bm.Width, bm.Height));
                string saveAsName;
                saveAsName = Regex.Replace(txtURL.Text, @"(\\|\/|\:|\*|\?|\""|\<|\>|\|)?", "");
                bm.Save(saveAsName + ".png", System.Drawing.Imaging.ImageFormat.Png);
                bm.Dispose();
            }
            catch (Exception e)
            {
                MessageBox.Show(e.Message, "保存失败", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            finally
            {
            }
            btnOK.Enabled = true;
        }        private void buttonCapture_Click(object sender, EventArgs e)
        {
            webBrowser1.Navigate(txtURL.Text);
            btnOK.Enabled = false;
        }
