Parameters

BarcodeNo
Barcode index. Must be between 1 and Barcode1DReaderGetBarcodeCount returned value.

Return Value

The barcode data.
Remarks

This method is used in the "Barcode Recognition" Demo.

For UCC / EAN-128 codes FNC1 control character is mapped to the <GS> char (ASCII code 29).

Example
Finding all 1D barcodes in a given image and saving their information to a file. 
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())

{

    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg");

 

    // Specify 1D barcode search types to be Code39 and Code128.

    Barcode1DReaderType barcodeType = Barcode1DReaderType.Barcode1DReaderCode39 | Barcode1DReaderType.Barcode1DReaderCode128;

 

    // Start the barcode scanning process. The ExpectedCount parameter is 0, all the barcodes should be retrieved.

    gdpictureImaging.Barcode1DReaderDoScan(imageID, Barcode1DReaderScanMode.BestQuality, barcodeType, false, 0);

 

    using (System.IO.StreamWriter file = new System.IO.StreamWriter("barcodes.txt"))

    {

        int barcodesFound = gdpictureImaging.Barcode1DReaderGetBarcodeCount();

        for (int i = 1; i <= barcodesFound; i++)

        {

            file.WriteLine(gdpictureImaging.Barcode1DReaderGetBarcodeValue(i));

        }

    }

 

    // Release used resources.

    gdpictureImaging.Barcode1DReaderClear();

    gdpictureImaging.ReleaseGdPictureImage(imageID);

}
