Example
Finding PDF417 barcodes in an image and writing complete barcodes info into a file.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", false);
 
    // Set to 0, so all the PDF417 barcodes in the image should be found.
    int expectedBarcodes = 0;
 
    // Perform scanning at best speed, ignoring very damaged barcodes.
    BarcodePDF417ReaderScanMode mode = BarcodePDF417ReaderScanMode.BestSpeed;
 
    // Start the PDF417 barcode scanning process and write info into a text file.
    gdpictureImaging.BarcodePDF417ReaderDoScan(imageID, mode, expectedBarcodes);
 
    using (System.IO.StreamWriter file = new System.IO.StreamWriter("PDF417.txt"))
    {
        int barcodesFound = gdpictureImaging.BarcodePDF417ReaderGetBarcodeCount();
 
        for (int i = 1; i <= barcodesFound; i++)
        {
            // Decoded information.
            file.WriteLine("Decoded info = " + gdpictureImaging.BarcodePDF417ReaderGetBarcodeValue(i));
 
            // The raw bytes decoded. It was post-processed to find the correct decoded info based on detected Encoding.
            file.WriteLine("Raw bytes = " + gdpictureImaging.BarcodePDF417ReaderGetBarcodeValueRAW(i));
 
            // The number of rows of the barcode.

            // The number of columns of the barcode.
            file.WriteLine("Columns = " + gdpictureImaging.BarcodePDF417ReaderGetBarcodeColumns(i));
 
            // The skew angle of the barcode, in degrees.
            file.WriteLine("Skew angle = " + gdpictureImaging.BarcodePDF417ReaderGetBarcodeSkewAngle(i));
 
            // Confidence in result, in percentage (values from 0 to 100).

        }
