作者:ranbolwb / 发布于2014/6/4/ 918


	string imgUrl = "http://www.baidu.com/img/baidu_sylogo1.gif"); //远程图片路径
	byte[] bytes = new System.Net.WebClient().DownloadData(imgUrl); //读取远程图片数据
	System.Drawing.Image image = System.Drawing.Image.FromStream(new System.IO.MemoryStream(bytes)); //将二进制转换为图片对象
	//对图片进行编辑
	System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(image);
	System.Drawing.Font font = new System.Drawing.Font("arial", 11, System.Drawing.FontStyle.Bold);
	System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Goldenrod);
	g.DrawString("ranbolwb", font, brush, new System.Drawing.PointF(0, 0));
	g.Save();
	g.Dispose();
	//图片保存及输出
	System.IO.MemoryStream ms = new System.IO.MemoryStream();
	image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
	context.Response.BinaryWrite(ms.ToArray());
	ms.Close();
	context.Response.End();
