復(fù)制主函數(shù)

接下來(lái)，將以下代碼插入主函數(shù)。

 

//Define variables

const char * pszImageFile = "";

int iIndex = 0;

int iRet = -1;

       

//Initialize license prior to any decoding

CBarcodeReader reader;

reader.InitLicense("");

 

//Initialize ReaderOptions

ReaderOptions ro = {0};          

ro.llBarcodeFormat = OneD;   //Expected barcode types to read.

ro.iMaxBarcodesNumPerPage = 100;     //Expected barcode numbers to read.

reader.SetReaderOptions(ro);

 

//Start decoding

iRet = reader.DecodeFile(pszImageFile);

 

//If not DBR_OK

if (iRet != DBR_OK)

{

  printf("Failed to read barcode: %d\r\n%s\r\n",iRet, GetErrorString(iRet));

  return iRet;

}

 

//If DBR_OK

pBarcodeResultArray paryResult = NULL;

reader.GetBarcodes(&paryResult);

printf("%d total barcodes found. \r\n", paryResult->iBarcodeCount);

for (iIndex = 0; iIndex < paryResult->iBarcodeCount; iIndex++)

{

  printf("Result %d\r\n", iIndex + 1);

  printf("PageNum: %d\r\n", paryResult->ppBarcodes[iIndex]->iPageNum);

  printf("BarcodeFormat: %lld\r\n", paryResult->ppBarcodes[iIndex]->llFormat);

  printf("Text read: %s\r\n", paryResult->ppBarcodes[iIndex]->pBarcodeData);

}

 

//Finally release BarcodeResultArray

CBarcodeReader::FreeBarcodeResults(&paryResult);

升級(jí)源圖片

改變圖片路徑。我將會(huì)用一個(gè)例子圖片Change the image path. I am going to use a sample image from the installation folder. Copy the file path, add the escape character, and then the file name. Change the path to "C:\\Program Files (x86)\\Dynamsoft\\Barcode Reader 4.1\\Images\\AllSupportedBarcodeTypes.tif".

 

const char * pszImageFile = "C:\\Program Files (x86)\\Dynamsoft\\Barcode

 Reader 4.1\\Images\\AllSupportedBarcodeTypes.tif";

             

Build the project. Build Succeeded.

復(fù)制條碼DLL

轉(zhuǎn)到安裝目錄，在Components \ C_C ++ \ Redist文件夾下，復(fù)制這兩個(gè)DLL - DynamsoftBarcodeReaderx86.dll和DynamsoftBarcodeReaderx64.dll。 將其粘貼到與BarcodeReaderC ++ API.exe相同的文件夾中，默認(rèn)情況下，該文件位于解決方案的Debug文件夾下。

按Ctrl + F5運(yùn)行項(xiàng)目。 好。 我們已經(jīng)識(shí)別所有的條形碼。
