The UCC/EAN-128 Symbology is a
subset of the more general Code 128 Symbology.
UCC/EAN-128 was developed to provide a worldwide format and standard for exchanging
common data between companies. While other bar codes simply encode data with no respect for
what the data represents, UCC/EAN-128 encodes data and encodes what that data represents.
UCC/EAN-128 has a list of Application Identifiers (AI). The
Application Identifier is a 2, 3, or 4-digit number that identifies the type of
data which follows. By convention, the Application Identifier is enclosed in
parentheses when printed below the barcode (the parentheses are only for visual
clarity, and are not encoded in the barcode).
Sample of a UCC/EAN-128 Barcode
How to encode UCC/EAN-128 values using Barcode Library
Introduction
UCC/EAN 128 encodes the so called Element Strings which are composed of an Application Identifier (AI)
plus a data field.
Each AI identifies the meaning and format of the data following it.
Note that the AI has parentheses around it in the human readable text,
but the parentheses are not encoded in the barcode.
Encode AI Code
In Barcode Library, developer mush put AI(dddd) around AI code, for the above sample image, you must
set data property = 'AI(21)d12345777AI(21)12345678'.
In Barcode Library, you can use CH(ddd) format to encode ASCII data, for example CH(100) = d.
So for the above sample image, you can also
set data property = 'AI(21)CH(100)12345777AI(21)12345678'.
There are two ways to create barcode images in your Java web applications.
This is the simplest way to stream barcode image using our provided barcode servlet classes.
And it will not save barcode images in your server side.
Under demo package, copy barcode folder to your java servlet container like tomcat.
To test your installation, goto http://YourDomain:Port/barcode/barcode?Data=123456789&Type=CODE39
To create barcode image in your JSP page, you can pass the url to IMG tag src value.
For example, <img src="http://YourDomain:Port/barcode/barcode?Data=123456789&Type=CODE39" />
The second method is similar with the way to generate barcode in Java applications.
View all supported barcode types and values. Use the number value for the java bean class and the number or text value for the servlet.
For example, the servlet query url should include:
Type=CODE128 or Type=22
data
Data
""
This is the barcode text to be encoded. The type is String.
EAN 8: User should only provide 7 digits, and DO NOT include last digit checksum character.
EAN 13: User should only provide 12 digits, and DO NOT include last digit checksum character.
UPCA: User should only provide 11 digits, and DO NOT include last digit checksum character.
UPCE: User should only provide 6 digits, and DO NOT include last digit checksum character.
sData
SData
""
Supplement data for ISBN, ISSN, EAN 8, EAN 13, UPCA, UPCE only. The type is String.
addCheckSum
AddCheckSum
true
Valid values are true and false. If barcode type check sum is compulsory or not applied, addCheckSum will not work. Please check each barcode symbologies to get more details.
processTilde
ProcessTilde
true
For barcode Code 128 only. Set the ProcessTilde property to true, if you want use the tilde character "~" to specify special characters in the input data. Default is true. ~NNN: is used to represent the ASCII character with the value of NNN.
Codabar
codabarStartChar
CodabarStartChar
A
One of four possible start characters (A, B, C, or D).
codabarStopChar
CodabarStopChar
A
One of four possible stop characters (A, B, C, or D).
UPC-E
UPCENumberSystem
UPCENumberSystem
0
Valid values are 0 and 1. The default is 0. UPC-E may only be used if the number system is 0 or 1. The characters encoded are encoded with odd and even parity from the left-hand columns of the EAN-13 character formats in the table previously provided. The parity used for each character depends on the number system (0 or 1) and the check digit from the original UPC-A barcode.
Barcode Image Style
uom
UOM
0 (pixel)
Unit of measure for barcode size settings, type is float, default is 0 (pixel). Valid values are 0 (pixel), 1 (CM), 2 (Inch)
resolution
Resolution
96
Image resolution. Default is 96 DPI.
barWidth
BarWidth
0
Bar cell width, type is float. Its unit of measure is decided by uom.
leftMargin
LeftMargin
0
The left margin. Its unit of measure is decided by uom.
rightMargin
RightMargin
0
The right margin. Its unit of measure is decided by uom.
topMargin
TopMargin
0
The top margin. Its unit of measure is decided by uom.
bottomMargin
BottomMargin
0
The bottom margin. Its unit of measure is decided by uom.
showText
ShowText
true
If this value is true (T in servlet), barcode data will be
displayed with the barcode. The servlet convert "T" to true and
"F" to false.
textFont
TextFont
Arial
The font used to display text in barcode image. To change the font, use the following
format:
Font font = new Font("Arial", Font.BOLD, 13);
barcode.setTextFont(font);
and to change the font in the servlet, use this format:
&TextFont=Arial|Bold|13
imageFormat
ImageFormat
gif
Valid values are "gif" and "jpeg". This setting is only valid in Servlet not in bean class.
rotate
Rotate
0
If you want to rotate barcode image.
Value can be
0 (Image Bottom Facing Down),
1 (Image Bottom Facing Left),
2 (Image Bottom Facing Up),
3 (Image Bottom Facing Right)
