BarcodeMicroQRReaderGetBarcodeX2 Method (GdPictureImaging)
Example 





GdPicture14 Namespace > GdPictureImaging Class : BarcodeMicroQRReaderGetBarcodeX2 Method
Barcode index. Must be between 1 and BarcodeMicroQRReaderGetBarcodeCount returned value.
Returns the X position (in pixels) of the top-right corner of a barcode detected by the BarcodeMicroQRReaderDoScan method. If ROI has been set, this coordinate is relative to the used ROI.

Example
Finding Micro Qr Code 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 Micro QR Codes in the image should be found.
    int expectedBarcodes = 0;
 
    // Perform scanning at best speed, ignoring very damaged barcodes.
    BarcodeQRReaderScanMode mode = BarcodeQRReaderScanMode.BestSpeed;
 
    // Start the Micro Qr Code scanning process and write info into a text file.
    gdpictureImaging.BarcodeMicroQRReaderDoScan(imageID, mode, expectedBarcodes);
 
    using (System.IO.StreamWriter file = new System.IO.StreamWriter("MicroQrCodes.txt"))
    {
        int barcodesFound = gdpictureImaging.BarcodeMicroQRReaderGetBarcodeCount();
 
        for (int i = 1; i <= barcodesFound; i++)
        {
            // Decoded information.
            file.WriteLine("Decoded info = " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeValue(i));
 
            // The skew angle of the barcode, in degrees.
            file.WriteLine("Skew angle = " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeSkewAngle(i));
 
            // Confidence in result, in percentage (values from 0 to 100).
            file.WriteLine("Confidence = " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeConfidence(i));
 
            // The version of a Micro Qr Code, in range 1-4. The higher the version, the larger the barcode is.
            file.WriteLine("Version = " + gdpictureImaging.BarcodeMicroQRReaderGetVersion(i));
 
            // The barcode position, given by the coordinates of the corners.
            file.WriteLine("Position =  Top-Left=["
                + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeX1(i) + ", " + gdpictureImaging.BarcodeMicroQRReaderGetBarcodeY1(i)

        }
    }
 
    // Release used resources.
    gdpictureImaging.BarcodeMicroQRReaderClear();
    gdpictureImaging.ReleaseGdPictureImage(imageID);
