Example
Finding MaxiCode in an image and writing complete barcodes info in a file. 
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", false);
 
    // Set to 0, so all the MaxiCode in the image should be found.
    int expectedBarcodes = 0;
 
    // Perform scanning at best speed, ignoring very damaged barcodes.
    BarcodeMaxiCodeReaderScanMode mode = BarcodeMaxiCodeReaderScanMode.BestSpeed;
 
    // Start the MaxiCode scanning process and write info into a text file.
    gdpictureImaging.BarcodeMaxiCodeReaderDoScan(imageID, mode, expectedBarcodes);
 
    using (System.IO.StreamWriter file = new System.IO.StreamWriter("MaxiCode.txt"))
    {
        int barcodesFound = gdpictureImaging.BarcodeMaxiCodeReaderGetBarcodeCount();
 
        for (int i = 1; i <= barcodesFound; i++)
        {
            // Decoded information.
            file.WriteLine("Decoded info = " + gdpictureImaging.BarcodeMaxiCodeReaderGetBarcodeValue(i));
 
            // The raw bytes decoded. It was post-processed to find the correct decoded info based on detected Encoding.
            file.WriteLine("Raw bytes = " + gdpictureImaging.BarcodeMaxiCodeReaderGetBarcodeValueRAW(i));
 
            // The barcode position, given by the coordinates of the corners.
            file.WriteLine("Position =  Top-Left=["
