FileIdNumberHighByte Property

Summary

Gets or sets a value that indicates the high byte of the file ID number to use when writing Datamatrix symbols.

Syntax

Objective-C

C++/CLI

Java

Python

public byte FileIdNumberHighByte { get; set; }

@property (nonatomic, assign) unsigned char fileIdNumberHighByte;

public byte getFileIdNumberHighByte() 
public void setFileIdNumberHighByte(byte value)

public: 
property byte FileIdNumberHighByte { 
   byte get(); 
   void set (    byte ); 
}

FileIdNumberHighByte # get and set (DatamatrixBarcodeWriteOptions)

Property Value

A Byte that indicates the high byte of the file ID number to use when writing Datamatrix symbols. Must be a value greater to or equal to 1 and less than or equal to 254. Default value is 1.

Remarks

Datamatrix barcodes support the concept of groups of related symbols. Use the following properties to write a group of related symbols:

GroupTotal - Specifies the total number of Datamatrix symbols in the group specified by GroupNumber. The maximum number of symbols in a group is 16.
GroupNumber - Specifies a group of Datamatrix symbols. The maximum number of symbols in a group is 16. Use this property to specify the order of each barcode in a group; hence, when you read each barcode's data, you can put large pieces of data back together in the correct order.
FileIdNumberLowByte - Specifies the low byte of the file ID number. The number must range from 1 to 254. Use this as an ID for the group since an image can have multiple groups.
FileIdNumberHighByte - Specifies the high byte of the file ID number. The number must range from 1 to 254. Use this as an ID for the group since an image can have multiple groups.
