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);

// The raw bytes decoded. It was post-processed to find the correct decoded info based on detected Encoding.
