Once your image has been acquired and pre-image processing has been performed to recognize the barcode on the image, some properties must first be set.

The recognition properties are defined in BX_AnalyzeParameters. BX_DefaultAnalyzeParameters is the defaults settings for recognizing barcodes.

Barcode Xpress for Linux detects all barcodes in an image and gives you complete details about them.

Supported Barcodes for Recognition

Barcodes supported for recognition are listed in the Overview of Barcode Xpress for Linux.

Once the BarcodeTypes property has been determined as stated in the Acquire an Image for Barcode Recognition topic, use the following methods and properties to recognize the barcode.

Methods

    // The BX_set_solution_name and BX_set_solution_key methods must be called to distribute the runtime.
    BX_set_solution_name("YourSolutionName");
    BX_set_solution_key(12345, 12345, 12345, 12345);

         // The BX_set_oem_license_key is required if Manually Reported Runtime Licensing is used.
    // BX_set_oem_license_key("2.0.AStringForOEMLicensing");

         // Initialize default analyze parameters and prepare result holder
    BX_AnalyzeParameters params = BX_DefaultAnalyzeParameters;
    BX_AnalyzeResult result;
    BX_Status status;

         // call BX_analyze_file, BX_analyze_dib, or BX_analyze_bmp to detect barcodes in the image
    status = BX_analyze_file( &params, fileName, &result );
    if( BX_Status_OK != status ) {
        printf("ERRORS:\n");
        for( int i=0; i<result.ErrorCount; ++i ) {
            BX_Error *error = &(result.BarcodeErrors[i]);
            printf("\t%d: %s\n\t%s\n", error->errorStatus, error->errorID, error->errorMessage);
        }
        return;
    }

         if( 0 == result.BarcodeResultsLength ) {
        printf("No results\n");
        BX_free_analyze_result( &result );
        exit(0);
    }

         // all detected barcodes will be returned to the
    // BarcodeResults object array.
    for( int i=0; i<result.BarcodeResultsLength; ++i ) {
        BX_BarcodeResult *res = &result.BarcodeResults[i];
        printf("Result #%d\n", i+1);
        printf("\tValue: %s\n", res->Value);
    }

         // Free results' data
    BX_free_analyze_result( &result );
