Great thanks to IEEE by his Project IEEE/QQImpl] and article.
This project is based on it and reduced the product size by using protobuf-lite instead of protobuf.
This project provided a direct Python interface for calling in sync mode as well as other languages support including but not limited with c++/java/c#.
To work with this project, you need to prepare the wechat OCR binary and the wechat runtime folder.
For wechat 3.x, the wechat OCR binary is wechatocr.exe, it might be:
C:\Users\yourname\AppData\Roaming\Tencent\WeChat\XPlugin\Plugins\WeChatOCR\7061\extracted\WeChatOCR.exe
and the wechat runtime folder might be:
C:\Program Files (x86)\Tencent\WeChat\[3.9.8.25]
Wechat 4.0 is now supported!
For wechat 4.0, the wechat OCR binary is wxocr.dll, it might be:
C:\Users\yourname\AppData\Roaming\Tencent\xwechat\XPlugin\plugins\WeChatOcr\8011\extracted\wxocr.dll
and the wechat runtime folder might be:
C:\Program Files\Tencent\Weixin\4.0.0.26
WeChat 4.0 OCR binary is wxocr.dll, but this project built a DLL named wcocr.dll
Their names are similar, DO NOT confuse them.
Typically, You should use /opt/wechat/wxocr as the OCR exe path and /opt/wechat/ as the WeChat folder path.
The other usages are similar to those on Windows.
You can use the following code to test it:
CWeChatOCR ocr(wechatocr_path, wechat_path);
if (!ocr.wait_connection(5000)) {
// error handling
}
CWeChatOCR::result_t result;
ocr.doOCR("D:\\test.png", &result);You can also pass nullptr to the second parameter of doOCR to call in async mode and wait the callback.
In this case, you need to subclass CWeChatOCR and implement the virtual function OnOCRResult.
Rename the built wcocr.dll to wcocr.pyd and put it in the same directory as test.py.
You can use the following code to test it:
import wcocr
wcocr.init(wechatocr_path, wechat_path)
result = wcocr.ocr("D:\\test.png")Currently, the python interface only supports sync mode.
- see java/Test.java
- I'm not so familiar with java and don't know how to pass complex data structures, so I just passed a JSON string from cpp to java.
- The added DLL export function
wechat_ocrcan also be used in other scenarios.
- see
c_sharpfolder. - It's important to ensure the built dll is copied to the folder test_cs.exe in! always copy the 64bit version dll!
- It's ok to built a 32bit test_cs.exe and copy the 32bit dll, you can try.
