Create a Barcode

The first step to creating a barcode is to decide what type of barcode to use and what the contents will be. This is done by creating a BX_CreateParameters structure.

Set the type of barcode and the value you want to create. Barcode types that can be written are listed in the Supported Barcode Types section.

For a full list of properties see the BX_CreateParameters structure.

To create a bitmap image file of the barcode call the BX_create_file function.

To create an in memory bitmap structure of the barcode call the BX_create_dib function.

The following code example illustrates creating a 1D barcode.

	Copy Code
//create a copy of the default parameters. BX_CreateParameters bxCreateParams = BX_DefaultCreateParameters; //set some of the 1D parameters: bxCreateParams.Params1D.CheckSum = false; //don't print the checksum for barcode types that have an optional checksum character. bxCreateParams.Params1D.TextNotchPercent = 25; // create the status and results variable to capture the results: BX_CreateResult createResult; BX_Status resultOfCreation = BX_Status_OK; // initialize the error count: createResult.ErrorCount = 0; //call BX_create_dib or BX_create_file to create a barcode image: resultOfCreation = BX_create_file(params, fl, &createResult); // check that the file was created successfully. if (createResult.ErrorCount == 0 && resultOfCreation == BX_Status_OK) { printf("Successfully created file \"%s\".\n", fl); } else { ///there was an error of some kind: printf("Failed to create file %s. ErrorNumber = %d\n", fl, resultOfCreation ); //print the error details: for (resultLen; resultLen < createResult.ErrorCount; resultLen++) { printf("Error creating file file %d: %s.\n", resultLen, createResult.BarcodeErrors[resultLen].errorID); } }

Copy Code

    //create a copy of the default parameters.
    BX_CreateParameters bxCreateParams = BX_DefaultCreateParameters;
    //set some of the 1D parameters:
    bxCreateParams.Params1D.CheckSum = false; //don't print the checksum for barcode types that have an optional checksum character.
    bxCreateParams.Params1D.TextNotchPercent = 25;
    // create the status and results variable to capture the results:
    BX_CreateResult createResult;
    BX_Status resultOfCreation = BX_Status_OK;
    // initialize the error count:
    createResult.ErrorCount = 0;
   
    //call BX_create_dib or BX_create_file to create a barcode image:
    resultOfCreation = BX_create_file(params, fl, &createResult);
   
    // check that the file was created successfully.
    if (createResult.ErrorCount == 0 && resultOfCreation == BX_Status_OK)
    {
        printf("Successfully created file \"%s\".\n", fl);
    }
    else
    {
        ///there was an error of some kind:
        printf("Failed to create file %s. ErrorNumber = %d\n", fl, resultOfCreation );
        //print the error details:
        for (resultLen; resultLen < createResult.ErrorCount; resultLen++)
        {
            printf("Error creating file file %d: %s.\n", resultLen, createResult.BarcodeErrors[resultLen].errorID);
        }
    }
