Example
Finding patch codes in an image and writing complete barcodes info into a file. 
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())

{

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

 

    // Start the patch codes scanning process and write complete information into a text file.

    gdpictureImaging.PatchCodeReaderDoScan(imageID);

 

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

    {

        int patch codesFound = gdpictureImaging.PatchCodeReaderGetCodeCount();

 

        for (int i = 1; i <= patch codesFound; i++)

        {

            // Patch codes type, possible values are 1, 2, 4, 8, 16 or 32.

            PatchCodeType type = gdpictureImaging.PatchCodeReaderGetCodeType(i);

            file.WriteLine("Patch code type = " + type.ToString());

 

            // The patch code position, given by the coordinates of the corners.

            file.WriteLine("Position =  Top-Left=["
