Remarks

The MaxiBarcodeData class derives from the base BarcodeData to add specific data that can be read or written when using Maxi barcodes.

Reading Barcodes

When the BarcodeReader object detects and reads a Maxi ( BarcodeSymbology.Maxi), the BarcodeReader.ReadBarcode and BarcodeReader.ReadBarcodes methods will return the MaxiBarcodeData object for each barcode cast down to the base BarcodeData class.

You can perform standard .NET casting to get the object as MaxiBarcodeData and then examine the extra data properties associated with it.

Maxi read options not related to the barcode data can be set using the MaxiBarcodeReadOptions class.

Writing Barcodes

The BarcodeWriter class contains the WriteBarcode method that is used to write a barcode to an image. This method accepts the data parameter as the base BarcodeData object. To write a Maxi barcode, create an instance of MaxiBarcodeData and fill the required parameters, then pass this object as the data parameter to WriteBarcode.

Maxi write options not related to the barcode data can be set using the MaxiBarcodeWriteOptions class.

You can use the static (or Shared in VB) BarcodeData.CreateDefaultBarcodeData method to create a new instance of MaxiBarcodeData that contains default parameters ready for writing to an image:

vb[VB Snippet] 
Dim MaxiData As MaxiBarcodeData = DirectCast(BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.Maxi), MaxiBarcodeData) 
C# Snippet
MaxiBarcodeData MaxiData = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.Maxi) as MaxiBarcodeData; 
Example

This example writes a couple of Maxi barcodes with different options to an image and then reads them back.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void MaxiBarcode_Example() 
{ 
	string imageFileName = Path.Combine(LEAD_VARS.ImagesDir, "MyMaxiBarcodes.tif"); 
 
	BarcodeEngine engine = new BarcodeEngine(); 
 
	// Create the image to write the barcodes to 
	int resolution = 300; 
	using (RasterImage image = RasterImage.Create((int)(8.5 * resolution), (int)(11.0 * resolution), 1, resolution, RasterColor.FromKnownColor(RasterKnownColor.White))) 
	{ 
		// Write two Maxi barcodes 
		WriteBarcode(engine.Writer, image, MaxiBarcodeSymbolModel.MaxiCodeMode4, "Maxi Data 1", 0); 
		WriteBarcode(engine.Writer, image, MaxiBarcodeSymbolModel.MaxiCodeMode5, "Maxi Data 2", 1000); 
 
		// Save the image 
		using (RasterCodecs codecs = new RasterCodecs()) 
		{ 
			codecs.Save(image, imageFileName, RasterImageFormat.CcittGroup4, 1); 
		} 
	} 
 
	// Now read the barcodes again 
	using (RasterCodecs codecs = new RasterCodecs()) 
	{ 
		using (RasterImage image = codecs.Load(imageFileName)) 
		{ 
			// Read all the Maxi barcodes 
			ReadBarcodes(engine.Reader, image); 
		} 
	} 
} 
 
private void WriteBarcode(BarcodeWriter writer, RasterImage image, MaxiBarcodeSymbolModel symbolModel, string value, int startRow) 
{ 
	// Create the barcode data 
	MaxiBarcodeData barcode = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.Maxi) as MaxiBarcodeData; 
	barcode.Value = value; 
 
	// We will use the alignment to position the barcodes, so use all of the image 
	barcode.Bounds = new LeadRect(0, startRow, image.ImageWidth, image.ImageHeight); 
 
	// Set the write options 
	MaxiBarcodeWriteOptions options = new MaxiBarcodeWriteOptions(); 
 
	options.Resolution = 600; 
	options.SymbolModel = symbolModel; 
 
	// Write it 
	Console.WriteLine("Writing barcode with symbol model: {0} and Data: {1}", symbolModel, value); 
	writer.WriteBarcode(image, barcode, options); 
} 
 
private void ReadBarcodes(BarcodeReader reader, RasterImage image) 
{ 
	// Setup read options 
	MaxiBarcodeReadOptions options = new MaxiBarcodeReadOptions(); 
 
	Console.WriteLine("Reading Maxi barcodes"); 
	BarcodeData[] barcodes = reader.ReadBarcodes(image, LeadRect.Empty, 0, new BarcodeSymbology[] { BarcodeSymbology.Maxi }, new BarcodeReadOptions[] { options }); 
	Console.WriteLine("{0} barcodes found:", barcodes.Length); 
	foreach (MaxiBarcodeData barcode in barcodes) 
	{ 
		Console.WriteLine(" At {0}, and data: {1}", barcode.Bounds, barcode.Value); 
	} 
}
