在asp.net中编写上传图片并同时生成带有版权信息的缩略图程序 <%@ Page Language="C#" ResponseEncoding="gb2312" %> <%@ import Namespace="System" %> <%@ import Namespace="System.IO" %> <%@ import Namespace="System.Drawing" %> <%@ import Namespace="System.Drawing.Imaging" %> <script runat="server"> void Page_Load(Object sender, EventArgs e) { if(!Page.IsPostBack) { ImgPreview.Visible=false; } } void GetThumbnailImage(int width,int height,string strInfo,int left,int right) { string file="Uploads/"+uploadFile.PostedFile. FileName.Substring(uploadFile.PostedFile.FileName.LastIndexOf('\\')+1); string newfile="Uploads/"+uploadFile.PostedFile. FileName.Substring(uploadFile.PostedFile.FileName.LastIndexOf('\\')+1)+".jpg"; string strAdd=strInfo; System.Drawing.Image oldimage = System.Drawing.Image.FromFile(Server.MapPath(file)); System.Drawing.Image thumbnailImage = oldimage.GetThumbnailImage(width, height,new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback), IntPtr.Zero); Response.Clear(); Bitmap output=new Bitmap(thumbnailImage); Graphics g=Graphics.FromImage(output); g.DrawString(strAdd,new Font("Courier New", 14),new SolidBrush(Color.Red),left,right); output.Save(Server.MapPath(newfile),System.Drawing.Imaging.ImageFormat.Jpeg); Response.ContentType = "image/gif"; ImgPreview.Visible=true; ImgPreview.ImageUrl=newfile; } bool ThumbnailCallback() { return true; } void Button_Click(object sender, EventArgs e) { int width,height,left,right; string strAddInfo=txtAddInfo.Text; width=Int32.Parse(txtWidth.Text); height=Int32.Parse(txtHeight.Text); left=Int32.Parse(txtLeft.Text); right=Int32.Parse(txtRight.Text); if(!(uploadFile.PostedFile.ContentLength>0)) { lblErrInfo.Text="没有选择文件"; } else { 未完！！！！！！！
