Example 





GdPicture14 Namespace > GdPictureImaging Class : BarcodeAztecReaderGetBarcodeY1 Method
Barcode index. Must be between 1 and BarcodeAztecReaderGetBarcodeCount returned value.
Returns the Y position (in pixels) of the top-left corner of a barcode detected by the BarcodeAztecReaderDoScan method. If ROI has been set, this coordinate is relative to the used ROI.

Example
Finding Aztec barcodes 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 Aztec barcodes in the image should be found.
    int expectedBarcodes = 0;
 
    // Perform scanning at best speed, ignoring very damaged barcodes.
    BarcodeAztecReaderScanMode mode = BarcodeAztecReaderScanMode.BestSpeed;
 
    // Start the Aztec barcode scanning process and write info into a text file.
    gdpictureImaging.BarcodeAztecReaderDoScan(imageID, mode, expectedBarcodes);
 
    using (System.IO.StreamWriter file = new System.IO.StreamWriter("Aztec.txt"))
    {
        int barcodesFound = gdpictureImaging.BarcodeAztecReaderGetBarcodeCount();
 
        for (int i = 1; i <= barcodesFound; i++)
        {
            // Decoded information.
            file.WriteLine("Decoded info = " + gdpictureImaging.BarcodeAztecReaderGetBarcodeValue(i));
 
            // The raw bytes decoded. It was post-processed to find the correct decoded info based on detected Encoding.
            file.WriteLine("Raw bytes = " + gdpictureImaging.BarcodeAztecReaderGetBarcodeValueRAW(i));
 
            // The barcode position, given by the coordinates of the corners.
            file.WriteLine("Position =  Top-Left=["
                + gdpictureImaging.BarcodeAztecReaderGetBarcodeX1(i) + ", " + gdpictureImaging.BarcodeAztecReaderGetBarcodeY1(i)
