利用ASPUPLOAD，ASPJPEG实现图片上传自动生成缩略图及加上水印
今天在站长站看到一网友写的相册程序，功能挺简单的，看到他用了ASPJPEG生成缩略图，不由想起再用上ASPUPLOAD上传，于是花了一个小时时间完善了他的代码。
以下代码均加有简单的注释，如果你看不懂，请先看ASPJPEG以及ASPUPLOAD的说明文档（E文，希望有心理准备），看不懂的可以问我。
以下是代码：
复制代码 代码如下:
<% if session("admin")<>"on" then Response.Redirect"login.asp" end if %> <!--#include file="config.asp" --> <!--#include file="mdb/conn.asp" --> <% Set Upload = Server.CreateObject("Persits.Upload") FilePath=Server.MapPath(".") Count = Upload.Save(FilePath&BigPhotoPath) '传大图 SmallFilePath=FilePath & SmallPhotoPath For Each File in Upload.Files Set Jpeg = Server.CreateObject("Persits.Jpeg") Jpeg.Open (File.Path) BigFP=BigPhotoPath&(File.FileName) '大图相对路径 SFP=SmallPhotoPath&"S_"&(File.FileName)'小图相对路径 FileSize=File.Size'备写入数据库 '开始判断哪边为长边，以长边进行缩放,并生成小图 imgWidth=Jpeg.OriginalWidth imgHeight=Jpeg.OriginalHeight if imgWidth>=imgHeight and imgWidth>120 then Jpeg.Width=150 Jpeg.Height=Jpeg.OriginalHeight/(Jpeg.OriginalWidth/150) end if if imgHeight>imgWidth and imgHeight>113 then Jpeg.Height=113 Jpeg.Width=Jpeg.OriginalWidth/(Jpeg.OriginalHeight/113) end if Jpeg.Sharpen 1, 130 Jpeg.Save (SmallFilePath&"S_"&File.FileName) '给大图加上水印(仅对大图加水印) Jpeg.Open Server.MapPath(""&BigFP&"") Jpeg.Canvas.Font.Color = &HFF0000 Jpeg.Canvas.Font.Family = "Courier New" Jpeg.Canvas.Pen.Color = &H000000 Jpeg.Canvas.Pen.Width = 2 Jpeg.Canvas.Brush.Solid = False Jpeg.Canvas.Font.BkMode = "Opaque" '处理平滑 Jpeg.Canvas.PrintText 10, 10, "www.LuanLuan.cn" 'Jpeg.Canvas.DrawBar 1, 1, 100, 100 Jpeg.Save Server.MapPath(BigFP) Next strSQL= "insert into desktop ([name],typeid,zhuanti,jj,[time],imgh,imgw,filesize,url,surl) values ('"&Upload.Form("name")&"','"&Upload.Form("typeid")&"','"&Upload.Form("zhuanti")&"','"&Upload.Form("photointro")&"','"&Now()&"','"&imgheight&"','"&imgwidth&"','"&FileSize &"','"&BigFP&"','"&SFP&"')" conn.execute strSQL set upload=nothing '删除对象 typeid=Request.QueryString("typeid") response.write "<SCRIPT language=JavaScript>alert('文件上传成功,返回！');" response.write "this.location.href='addfile.asp?typeid="&typeid&"';</SCRIPT>" function HTMLEncode2(fString) fString = Replace(fString, CHR(13), "") fString = Replace(fString, CHR(10) & CHR(10), "</P><P>") fString = Replace(fString, CHR(10), "<BR>") HTMLEncode2 = fString end function %>
