aspjpeg组件实现加水印函数的调用方法：
<%printwater "/images/水印图片.gif","/uploadfile/上传图片.jpg") %>
代码如下:
function printwater(waterpath,upfilepath)
Dim Logobox,LogoPath,ogvbox
LogoPath = Server.MapPath(waterpath)
Set Logobox = Server.CreateObject("Persits.Jpeg")
Logobox.Open LogoPath
Logobox.Width = 108
Logobox.Height = 65
Set ogvbox = Server.CreateObject("Persits.Jpeg")
ogvbox.Open Trim(Server.MapPath(upfilepath))
ogvbox.Canvas.Pen.Color = &H000000 ''//增加水印后图片的边框色彩。
ogvbox.Canvas.Pen.Width = 1 ''//增加水印后图片的边框宽度。
ogvbox.Canvas.Brush.Solid = False ''//边框内是否填充颜色，你可以试试看值为True时的效果^o^
ogvbox.DrawImage ogvbox.width-108, ogvbox.height-65, Logobox, 0.6
ogvbox.Canvas.Bar 0, 0, ogvbox.Width, ogvbox.Height
ogvbox.Save Server.MapPath(upfilepath)
Set Logobox=Nothing
Set ogvbox=Nothing
end function
