asp中上传图片添加水印和缩略怎么实现？

'************加文字水印**********************

Public Function AddPersitsText(Path,Font,Location)

Dim Jpeg

Set Jpeg = Server.CreateObject("Persits.Jpeg")

Jpeg.Open Server.MapPath(Path) '打开图片,Path为路片路径及名称

Jpeg.Canvas.Font.Color = &HFF0000 '后6位为文字颜色

Jpeg.Canvas.Font.Family = "黑体" '文字字体

Jpeg.Canvas.Font.Bold = True '是否加粗

Jpeg.Canvas.Font.Size = 18 '字体大小

Jpeg.Canvas.Font.Quality = 10

Jpeg.Canvas.Font.ShadowXOffset = 1

Jpeg.Canvas.Font.ShadowYOffset = 3 '阴影效果

Jpeg.Canvas.Pen.Color = &HFFFFFF '水印背景颜色

Jpeg.Canvas.Pen.Width = 3

Jpeg.Canvas.Brush.Solid = False

IF Location =0 Then

Jpeg.Canvas.Print (Jpeg.width-60)/2, (Jpeg.height-10)/2, Font '水印显示在图片上的居中位置

ElseIf Location=1 Then

Jpeg.Canvas.Print Jpeg.width-120, 20, Font '水印显示在图片上的右上位置

ElseIF Location=2 Then

Jpeg.Canvas.Print Jpeg.width-120, Jpeg.height-20, Font '水印显示在图片上的右下位置

ElseIF Location=3 Then

Jpeg.Canvas.Print 20, 20, Font '水印显示在图片上的左上位置

Else

Jpeg.Canvas.Print 20, Jpeg.height-20, Font '水印显示在图片上的左下位置

End IF

Jpeg.Save Server.MapPath(Path) '保存水印图片

Set Jpeg = Nothing

End Function

'传入的参数是需要处理的图片路径，自己根据需要可以调整参数或者加入其它的参数

'文字水印

Function WordWatermark(ImagePath)

Dim Image

Set Image= Server.CreateObject("Persits.Jpeg") ' 建立对象

Image.Open server.mappath(ImagePath) ' 图片所在位置

Image.Canvas.Font.Color = &H000000 ' 颜色,这里是设置成:黑

Image.Canvas.Font.Family = "宋体" ' 设置字体

Image.Canvas.Font.Bold = False '是否设置成粗体

Image.Canvas.Font.Size = 26 '字体大小

Image.Canvas.Font.Quality = 4 ' 文字清晰度

Image.Canvas.Print Image.OriginalWidth/2-170,Image.OriginalHeight-30, "水印文字" '水印文字

Image.Save server.mappath(ImagePath) ' 保存文件

Set Image= Nothing

End Function

'图片水印

Function ImageWatermark(ImagePath)

Set Image = Server.CreateObject("Persits.Jpeg")

'确定要加入水印的图片路径

PhotoPath = Server.MapPath(ImagePath)

Image.Open PhotoPath

'打开水印图片

Set Logo = Server.CreateObject("Persits.Jpeg")

LogoPath = Server.MapPath("logo.jpg") '水印的图片

Logo.Open LogoPath

Logo.Width = 121 '水印图片的大小

Logo.Height = 50

Transition_Color = &h0066cc

'将水印放置于上传图片中

Image.DrawImage Image.width-150, Image.height-59, Logo,1,Transition_Color,90

'在这里可以更改水印所在的位置（photo.width-210,photo.height-40 这里我是放在了图片的右下角）还可以更改水印的透明度

'保存增加水印后的图片

Image.Save Server.MapPath(ImagePath)

Set Photo = Nothing

End Function

给全站图片加水印，思路是，找出网站图片目录，循环遍历该目录将里面的图片通过一个加水印函数处理,不明hi我或Q我:573780643
