我这有一篇文章,已经用html把样式设置好想转成图片,要求保留文章的样式,有没有哪位大侠知道怎么做??
我这有个现成的代码是根据url把该网页转成图片的,太高深了不知道能不能改。前台调用
protected void Page_Load(object sender, EventArgs e)
{
Bitmap m_Bitmap = WebSiteThumbnail.GetWebSiteThumbnail("http://www.baidu.com",1024,768,1024, 768);
MemoryStream ms = new MemoryStream();
m_Bitmap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);//JPG、GIF、PNG等均可
byte[] buff = ms.ToArray();
Response.BinaryWrite(buff);
}WebSiteThumbnail.cs 文件内容using System;
