接14楼，单色图的提取稍微麻烦些，他里面只有数据部分而缺少文件头，这个是比较头疼的事情
I7 a+ L9 {; X" s/ ]8 v先用ebdump提取出词典文本（本文），然后在里面获取单色图的代码(<1F44>开头，<1F64>结尾)
6 v5 E+ {; }! W+ ]" |# X可以看到
) j1 G+ B6 }# X# M) o<1F44><0001><w=200,h=256>xxx<1F64>[0001A4BD:0027]
9 h$ E. m5 r) U这里的w=200,h=256表示图片的尺寸，这个参数后面会用到' f- M/ N, e. l2 l. E5 d2 O# H7 |
然后<1F64>后面的这一段[0001A4BD:0027]就是单色图数据地址了
" c5 R/ U, Q! W- X! u' f6 ~先写个Demo 把所有地址都提取出来，顺便排一下序，去掉重复:
