使用PHP或JavaScript

單個圖像讀取多個條形碼有什麼辦法可以在使用PHP或JavaScript時間從一個單一的圖像掃描多個條形碼。我已經使用Google搜索，但只能掃描圖像中的單個條形碼。使用PHP或JavaScript

我曾嘗試這樣的代碼：https://gist.github.com/tobytailor/421369

我已經從這個鏈接複製代碼：https://gist.github.com/tobytailor/421369 –

請編輯的問題，並提到在它的鏈接。它會讓你的問題更清楚。 – captainsac

如果你不能找到任何好的PHP或JavaScript條碼的SDK，你可以嘗試一些C/C++軟件開發工具包。我只是向你展示一個關於如何在JavaScript和PHP中封裝C/C++方法的例子。

這裏是具有多個條形碼圖像。 enter image description here

您可以使用Dynamsoft Barcode SDK來解碼圖像並將所有返回的結果轉換爲JavaScript或PHP數據類型。

對於JavaScript：

#include <node.h> 

#include "If_DBR.h" 
#include "BarcodeFormat.h" 
#include "BarcodeStructs.h" 
#include "ErrorCode.h" 


#ifdef _WIN64

#else 
#pragma comment(lib, "DBRx86.lib") 
#endif 

using namespace v8; 

void SetOptions(pReaderOptions pOption, int option_iMaxBarcodesNumPerPage, int option_llBarcodeFormat){ 

    if (option_llBarcodeFormat > 0) 
     pOption->llBarcodeFormat = option_llBarcodeFormat; 
    else 
     pOption->llBarcodeFormat = OneD; 

    if (option_iMaxBarcodesNumPerPage > 0) 
     pOption->iMaxBarcodesNumPerPage = option_iMaxBarcodesNumPerPage; 
    else 
     pOption->iMaxBarcodesNumPerPage = INT_MAX; 

} 

void DecodeFile(const FunctionCallbackInfo<Value>& args) { 

    Isolate* isolate = Isolate::GetCurrent(); 
    HandleScope scope(isolate); 

    // convert v8 string to char * 
    String::Utf8Value utfStr(args[0]->ToString()); 
    char *pFileName = *utfStr; 

    int option_iMaxBarcodesNumPerPage = -1; 
    int option_llBarcodeFormat = -1; 

    pBarcodeResultArray pResults = NULL; 
    ReaderOptions option; 
    SetOptions(&option, option_iMaxBarcodesNumPerPage, option_llBarcodeFormat); 

    // decode barcode image file 
    int ret = DBR_DecodeFile(
     pFileName, 
     &option, 
     &pResults 
     ); 

    if (ret == DBR_OK){ 
     int count = pResults->iBarcodeCount; 
     pBarcodeResult* ppBarcodes = pResults->ppBarcodes; 
     pBarcodeResult tmp = NULL; 

     // javascript callback function 
     Local<Function> cb = Local<Function>::Cast(args[1]); 
     const unsigned argc = 1; 

     // array for storing barcode results 
     Local<Array> barcodeResults = Array::New(isolate); 

     for (int i = 0; i < count; i++) 
     { 
      tmp = ppBarcodes[i]; 

      Local<Object> result = Object::New(isolate); 
      result->Set(String::NewFromUtf8(isolate, "format"), Number::New(isolate, tmp->llFormat)); 
      result->Set(String::NewFromUtf8(isolate, "value"), String::NewFromUtf8(isolate, tmp->pBarcodeData)); 

      barcodeResults->Set(Number::New(isolate, i), result); 
     } 

     // release memory 
     DBR_FreeBarcodeResults(&pResults); 

     Local<Value> argv[argc] = { barcodeResults }; 
     cb->Call(isolate->GetCurrentContext()->Global(), argc, argv); 
    } 
} 

void Init(Handle<Object> exports) { 
    NODE_SET_METHOD(exports, "decodeFile", DecodeFile);

NODE_MODULE(dbr, Init)

您還可以使用HP IDOL OnDemand（我爲HP工作）中的一個Barcode Recognition API。我跑上面的圖片通過一個快速測試在線的控制檯，並能夠從圖像中提取文件的以下信息...
