动画图片制作软件处理工具

个动画制作软件(Gif Movie Gear3.0.2的PJ)的PJ过程与注册码算法。献给初学者。 下载地址：http://www.skycn.com/download.php?id=2418&url=http://ln.skycn.net/down/gmvgr30.exe 此版本的注册与3.0相与有了较大的改进，再也不是3.0的明码比较了，它的注册码与你所所输入的用户名有密切联系，可以通过用户名反推出注册码，当然也可以通过注册码推出用户名。所以要想得出真正的注册码需费一番周折。 软件介绍：它是一个非常优秀的图片处理工具，是对动态gif压缩效果非常满意，是一个图片处理的小精灵 。超级动画制作程序。 工具：TRW2000 1、首先运行movgear.exe，填入用户名和注册码。注意注册码的前四位必须为mg37原因你就看下文吧。（最好前五位是mg37s,当然也无所谓了，这是我的习惯。) 2、再运行TRW2000，设置中断 BPX HMEMCPY, 3、回到movgear.exe注册画面，按OK，TRW2000拦截成功后按F12按9次（如果我没记错的话）再按F10就可到达此处。代码比较多，有关注册码的算法我已经注明了，你仔细看下文吧。 :0043197C 6850040000 push 00000450 :00431981 56 push esi :00431982 FFD7 call edi :00431984 50 push eax
