利用ASPUPLOAD，ASPJPEG实现图片上传自动生成缩略图及加上水印

答案：
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=>
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  
%> 

上一个：VBScript中变量作用域
下一个：Ajax+ASP和Flash+ASP数据读取取方法有些相似的实现方法
