这个类可以公开调用
1. ImgInfo_Height 取图片高度
2. ImgInfo_Width 取图片宽度
调用方法:
Dim NewObj,Pic_h,Pic_w
Set NewObj=New AspJpeg
Pic_h=NewObj.ImgInfo_Height("f:/test.jpg")
Pic_w=NewObj.ImgInfo_Width("f:/test.jpg")
Set NewObj=Nothing
Response.Write "This Picture's Height is "&Pic_h
Response.Write "This Picture's Width is "&Pic_w
Response.End
3. Img_Reduce 对指定图片缩小或放大并保存(可选择是否加水印,是否加框架)
必须定义声明 MathPathFrom,MathPathTo
默认为缩放至150X150 图案 如按比例缩放后图案小于该尺寸,则补充空白图片
默认文件自动覆盖
实例:
Dim NewObj,NewCommand
Set NewObj=New AspJpeg
NewObj.MathPathFrom="f:/test.jpg"
NewObj.MathPathTo="f:/reduce.jpg"
NewCommand=NewObj.Img_Reduce
Set NewObj=Nothing
If NewCommand<>"" then
Response.Write "Success"
Else
'图片操作过程中出现错误
Response.Write "Failed"
End If
4. Img_WaterMark 给指定图片添加水印
水印可以为图片 文字 或 2者结合
