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$ c4 G9 m" m0 w: V5 U# J8 e
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)
8 M& m6 @# \. M8 X可以看到
2 t$ Z1 f6 s7 ?! A/ X1 a# l+ N3 i<1F44><0001><w=200,h=256>xxx<1F64>[0001A4BD:0027]
Q7 ~% k) j$ c. S这里的w=200,h=256表示图片的尺寸，这个参数后面会用到
; U, }9 L8 W k; q3 E/ v3 f; W然后<1F64>后面的这一段[0001A4BD:0027]就是单色图数据地址了
6 l! J6 m) z. Z2 o- |0 {2 P }" Z先写个Demo 把所有地址都提取出来，顺便排一下序，去掉重复:- I; A4 P) P2 S6 D4 |. A& E2 i6 ^
- static void getMonoTag(String f) {/ g& K/ X4 V2 F& G- m% c
- try {4 T$ o7 c& G* l9 \
- BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(f+".txt"), "Shift_JIS"));
3 J. C# f2 |( C - BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(f+".mono.txt"), "UTF-8"));9 o6 D$ J$ J8 y+ q3 v# |
- String line;

- while (((line = reader.readLine()) != null)) {0 u2 v2 y) K) A, p" I4 a& ?
- while (line.contains("<1F64>")) {, }7 \/ c. }2 s6 L8 B" f
- line = line.substring(line.indexOf("<1F64>") + 6);, F- w" e4 d d. Z
- monos.add(line.substring(0, 15));
- }6 k. S2 P5 ~! r' j" k# h - }
. Y$ ]6 U/ B& P- J" C. x" j - }
- P6 @9 s: @3 t3 o - reader.close();" z N7 _: j2 R. m% f; ?* ^
- String[] monoa = new String[monos.size()];- a2 ^# w/ E( f
- monos.toArray(monoa);
6 L5 h, ~4 s. Q, L% M' x - Arrays.sort(monoa);0 J4 q$ q z- c) h4 O4 [) K
- String last = "";
8 F8 ]7 i0 y5 n- M E8 T) G8 l - for (int i=0; i<monoa.length; i++) {2 p" S# b& R" w
- if (!monoa[i].equals(last))& U) o _8 Z! m1 q( c& _/ Y9 |
- writer.write(monoa[i] + "\r\n");
u! X8 ~' }% M/ ~& l- ]% A - last = monoa[i];+ Y( c0 A# f" r- o, L' q- \( E

得到了一个.mono.txt的文件
$ q& Q: f3 H1 \& q$ u8 R5 R+ P4 u! T然后开始提取:5 G; J3 `: ^9 }! n7 @( O
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。 - -
