Tesseract OCR在单点触控中 [英] Tesseract OCR In monotouch

问题描述

如何在Iphone的单点触控应用程序中实现Tesseract OCR?

How do I implement the Tesseract OCR in a monotouch application for Iphone?

推荐答案

首先，您需要将库 port 移植到iOS并作为 static 库使用. Vikas的答案( Pocket-PCR )可能会派上用场(但我还没有尝试过)

First you need to have the library ported to iOS and available as a static library. That where Vikas' answer (Pocket-PCR) might comes handy (but I have not tried it).

接下来，您需要创建到库的C#绑定.

Next you'll need to create C# bindings to the library.

当API导出C函数时，您可以使用 normal .NET pinvokes，即使用

When the API is exports C functions you can use normal .NET pinvokes, i.e. using DllImport attributes.

如果提供了Objective-C API，则可以使用btouch工具创建绑定. 说明可在MonoTouch网站上找到.

When an Objective-C API is provided then you can create bindings using the btouch tool. Instructions are available on the MonoTouch web site.

但是(有点像 Tesseract 的情况)对于C ++库而言更为复杂.您要么首先需要创建一个C(或Objective-C)库，即可导出所需的功能，然后它们会绑定您自己的API.

However (and this looks to be the case for Tesseract) it's a bit more complex for C++ libraries. You'll either need to first create a C (or Objective-C) library that export the feature you need and them bind your own API.
