我有一个使用Tessnet2的应用程序。当我尝试调用其 Init 方法时,应用程序失败。
失败太可怕了——没有例外(ANY),没有任何错误痕迹,甚至没有“发送报告”窗口。该应用程序的进程刚刚删除。
有问题的代码是:
Recogniser = new Tesseract();
Recogniser.SetVariable("tessedit_char_whitelist", Whitelist);
Recogniser.SetVariable("unlv_tilde_crunching", false);
Recogniser.Init(null, "eng", false); // FAILURE IS HERE
几个可能有用的注释:
- Tessnet2 需要Visual C++ 2008 运行时。不确定它是否应该是 msvcm90.dll、msvcm80.dll。
- 该应用程序是桌面 WPF。
- 开发环境:VS 2008 SP、.NET 3.5 SP1
- 它以前工作过(我想我添加了 Web 引用来使用 SOAP Web 服务,但我试图删除它但没有结果)。
- 单元测试运行良好,没有失败。
从这些观察来看,这听起来像是 WPF 应用程序本身的问题。
我只有一条信息是调试期间的输出:
