有些caj文件转换失败

[wk-1999]

首先感谢作者的开发努力，嘉惠学林。实际使用中有一些文档转换失败，不知道什么原因，我用蓝奏云附上两篇失败文档。

这个应用只是 caj2pdf 的 wrapper，我刚才用 caj2pdf 命令行版本试了一下，转换失败，你可以自己试一下。

建议把这个 bug 汇报给上游。

好的我去反馈一下，谢谢您

According to "OSError: dlopen(./libjbigdec.so, 6): image not found", you are on Mac OS; you are missing two libraries. For windows, we provide binaries under "lib/bin" , libjbig2codec*.dll and libjbigdec*.dll . The source code is in lib/*.cc, and the build instructions are at the top of the files. There are two alternative ways of building libjbig2codec.so , via decode_jbig2data_x.cc depending on jbig2dec is easier for non-linux (unless you use homebrew to get poppler, etc).

"明堂制度研究——明堂制度的源流_张一兵.caj" looks corrupted. Please re-download wherever you get it from, and check.
