asp版圖形驗證碼，可自定義點陣信息，支持字符扭曲、傾斜、傾斜

http://blog.ii-home.cn 2009/1/23 10:38:55 admin 字體:大中小瀏覽 16301

代碼并非完全原創，

主要代碼是另一位不知名的朋友寫的，來源早已記不清楚了。

我加了一個 ChangeShape 和 Fill 函數，

ChangeShape 用于使字符扭曲、傾斜（左右隨機），

需要的朋友拿去試試，個人覺得效果還可以，

當然，我數學白癡，呵呵，不懂得變通，死腦筋，大家不要見笑。

反正眼下也沒有asp版圖形驗證碼支持扭曲，如果真需要就拿我這個頂一下吧。

保存下面代碼到code.asp,在需要顯示驗證碼的地方使用
<img src="code.asp" alt="驗證碼" />來顯示,使用session("qwbm")
來提取驗證碼

以下為效果與相關的代碼：

以下為詳細代碼
