Dynamsoft Barcode Reader C C++ API

复制主函数

接下来，将以下代码插入主函数。

 

//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);

升级源图片

改变图片路径。我将会用一个例子图片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.

复制条码DLL

转到安装目录，在Components \ C_C ++ \ Redist文件夹下，复制这两个DLL - DynamsoftBarcodeReaderx86.dll和DynamsoftBarcodeReaderx64.dll。 将其粘贴到与BarcodeReaderC ++ API.exe相同的文件夹中，默认情况下，该文件位于解决方案的Debug文件夹下。

按Ctrl + F5运行项目。 好。 我们已经识别所有的条形码。
