5、如何用AspJpeg組件進(jìn)行圖片合并？
AspJpeg 1.3+ enables you to place images on top of each other via the method DrawImage. To use this method, you must create two instances of the AspJpeg objects and populate both of them with images via calls to Open (or OpenBinary). When calling Canvas.DrawImage, the 2nd instance of AspJpeg is passed as an argument to this method, along with the X and Y offsets (in pixels):
使用該方法，您必需創(chuàng )建兩個(gè)AspJpeg實(shí)例對象
<%
Set Jpeg1 = Server.CreateObject("Persits.Jpeg")
Set Jpeg2 = Server.CreateObject("Persits.Jpeg")
Jpeg1.Open Server.MapPath("t.jpg")
Jpeg2.Open Server.MapPath("t1.jpg")
Jpeg1.Canvas.DrawImage 10, 10, Jpeg2 ' optional arguments omitted
jpeg1.save Server.mappath("tt.jpg")
%>

6、如何用AspJpeg組件進(jìn)行圖片切割？
AspJpeg 1.1+ is also capable of cutting off edges from, or cropping, the resultant thumbnails via the method Crop(x0, y0, x1, y1). The size of the cropped image is specified by the coordinates of the upper-left and lower-right corners within the resultant thumbnail, not the original large image.
<%
Set Jpeg = Server.CreateObject("Persits.Jpeg")
Jpeg.Open Server.MapPath("t.jpg")
jpeg.Crop 20, 30, jpeg.Width - 20, jpeg.Height - 10
jpeg.save Server.mappath("tt.jpg")
Response.write("<img src=tt.jpg>")
%>
7、如何用AspJpeg組件創(chuàng )建安全碼？
創(chuàng )建安全碼原理上和創(chuàng )建水印差不多。
<%
function make_randomize(max_len,w_n) 'max_len 生成長(cháng)度，w_n：0 可能包含字母，1：只為數字
    randomize
    for intcounter=1 to max_len
        whatnext=int((1-0+1)*rnd+w_n)
        if whatnext=0 then
            upper=122
            lower=97
        else
            upper=57
            lower=48
        end if
        strnewpass=strnewpass & chr(int((upper-lower+1)*rnd)+lower)
    next
    make_randomize=strnewpass
end function
