如何在上传的图片上写字(1)
很多时候需要在用户上传的图片上加上版权或者一些其他的附加文字信息，如何实现这样的功能，下面帖个简单实现的例子，起到抛砖引玉的作用。<%@ Page Language="C#" Debug="true" Trace="true"%><%@ Import Namespace="System.IO" %><%@ Import Namespace="System.Drawing" %><%@ Import Namespace="System.Drawing.Imaging" %><html><script runat =server> void UploadBtn_Click(Object sender, EventArgs e) { String filename; String filename1; String[] filename2; int q; filename=UploadFile.PostedFile.FileName ; filename2=filename.Split(new Char[] {'\\'}); q=filename2.GetUpperBound(0); filename1=filename2[q]; dis.Text="上传文件名："+filename1+"<br>"; UploadFile.PostedFile.SaveAs(Server.MapPath(filename1)); ImageEditor.Visible = true; dis.Text+="文件大小："+UploadFile.PostedFile.ContentLength+"字节数"; Image1.Src=filename1; } void UpdateBtn_Click(Object sender, EventArgs e) { String filename1; filename1=Image1.Src; System.Drawing.Image image = System.Drawing.Image.FromFile(Server.MapPath(filename1)); System.Drawing.Image newimage = new Bitmap(image.Width, image.Height, PixelFormat.Format32bppRGB);
