MaxiBarcodeData Class

Contains the data for a single Maxi barcode.
public class MaxiBarcodeData : BarcodeData 
@interface LTMaxiBarcodeData : LTBarcodeData<NSCopying> 
public class MaxiBarcodeData extends BarcodeData 
public ref class MaxiBarcodeData : public BarcodeData, System.ICloneable   
class MaxiBarcodeData(BarcodeData): 

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; 

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