使用ASP的jpeg组件，我们可以做出各种样式的漂亮的验证码，只是苦于目前大多数服务器的JPEG组件版本太低，无法消除文字而造成的毛边，除非用非透明模式去绘制字体，但这样又无法达到仿制discuz论坛验证码的目的，因此，暂且先不管这么多了，文字有毛边锯齿就先随着它，这并不能成为当前验证码的缺憾。-Use the ASP jpeg components, we can make a variety of beautiful styles verification code, but suffer most current version of the component is too low JPEG server, the text can not be eliminated caused by flash, unless the use of non-transparent mode to draw the font, but so they can not reach imitation discuz forum codes purposes, therefore, for the time being to matter so much, there is text on the first jagged edges along with it, this does not become a verification code defect.
