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
! P/ R) R8 U8 v- K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)( o% q. S2 G0 N) D% A3 h
可以看到6 ^0 f. X1 R- `3 p; [8 R6 w& u# H
<1F44><0001><w=200,h=256>xxx<1F64>[0001A4BD:0027]' N- k2 Z% f5 W |; o
这里的w=200,h=256表示图片的尺寸，这个参数后面会用到2 [( F) |1 C3 V" t: J
然后<1F64>后面的这一段[0001A4BD:0027]就是单色图数据地址了
T2 u4 m1 x \) |先写个Demo 把所有地址都提取出来，顺便排一下序，去掉重复:- T1 ^0 N+ ]6 o6 _2 |8 C5 q5 |
- static void getMonoTag(String f) {" a2 X5 Q W$ M+ [6 O/ L( {) T% u8 D

得到了一个.mono.txt的文件8 h4 y" X2 Z2 B& Q/ |& Z, F8 r
然后开始提取:+ Z: i/ c* i& B4 l7 Z2 @$ h9 g: B
上面有提到w=200,h=256这两个参数，不过epwing好像弄反了，200是高，256是宽。 - -; c7 Q r( _: r `& I
