1.制作.box档案文件.
tesseract [lang].[fontname].exp[num].tif [lang].[fontname].exp[num] -l yournewlanguage batch.nochop makebox
2.开始培训
tesseract [lang].[fontname].exp[num].tif [lang].[fontname].exp[num] box.train
或
tesseract [lang].[fontname].exp[num].tif [lang].[fontname].exp[num] box.train.stderr
不知道什么来的
training/set_unicharset_properties -U input_unicharset -O output_unicharset --script_dir=training/langdata
字体属性文件
<fontname> <italic> <bold> <fixed> <serif> <fraktur>
在<字体>是一个字符串命名的字体 ; <斜体>，<加粗>，<固定>，<衬线>和<哥特体>都是简单的0或1标志指示字体是与否的属性。
Example:
timesitalic 1 0 0 1 0
----在3.03，有一个默认的font_properties文件，涵盖3000字体（不一定准确）培训/langdata / font_properties。
shapeclustering 创建主控形状表的聚类形状并将其写入一个文件shapetable。
shapeclustering -F font_properties -U unicharset lang.fontname.exp0.tr lang.fontname.exp1.tr ...
----如果你得到错误信息，像这样的 "index >= 0 && index < size_used_:Error:Assert failed in genericvector.h, line 512" 添加shapetable文件到您的语言数据文件。
mftraining -F font_properties -U unicharset -O lang.unicharset lang.fontname.exp0.tr lang.fontname.exp1.tr ...
你的文件是通过unicharset_extractor以上产生的unicharset，和lang.unicharset是输出unicharset将给予combine_tessdata。mftraining将输出两个数据文件：inttemp（形状的原型）和pffmtable（每个字符的预期功能）。
输出normproto数据文件
cntraining lang.fontname.exp0.tr lang.fontname.exp1.tr ...
