Java Code 128 Generator Introduction

Code 128, also known as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, is a very capable linear barcode of excellent density, high reliability.

Generate and create Code 128 barcode using Java is one of the functions in OnBarcode's Barcode for Java Generating Java library (jar file), which supports generating & printing Code 128 and 20+ other linear & 2D bar codes in Java application and software.

Code 128 Generator and Reader library, SDK & application
Code 128 Generator components and software include Code 128 in .NET, Code 128 in C#, Code 128 in ASP.NET, Code 128 in VB.NET, Code 128 Generator.

This document is providing a detailed Java sample source code about generating Code 128 barcodes in Java class using Java Barcode generation component. Complete Code 128 custmoization settings is included in Java Code 128 generating guide.

 

Generate Code 128 Barcodes in Java

Generating Code 128 barcode in Java class example:

	Code128 barcode = new Code128();
	
	/*
	   Code 128 Valid data char set:
	        all 128 ASCII characters (Char from 0 to 127)
	*/
	barcode.setData("112233445566");
	
	//  Set the processTilde property to true, if you want use the tilde character "~"
	//  to specify special characters in the input data. Default is false.
	//  1) All 128 ISO/IEC 646 characters, i.e. characters 0 to 127 inclusive, in accordance with ISO/IEC 646.
	//       NOTE This version consists of the G0 set of ISO/IEC 646 and the C0 set of ISO/IEC 6429 with values 28 - 31
	//       modified to FS, GS, RS and US respectively.
	//  2) Characters with byte values 128 to 255 may also be encoded.
	//  3) 4 non-data function characters.
	//  4) 4 code set selection characters.
	//  5) 3 Start characters.
	//  6) 1 Stop character.
	barcode.setProcessTilde(false);
	
	// Code 128 Unit of Measure, pixel, cm, or inch
	barcode.setUom(IBarcode.UOM_PIXEL);
	// Code 128 barcode bar module width (X) in pixel
	barcode.setX(3f);
	// Code 128 barcode bar module height (Y) in pixel
	barcode.setY(75f);
	
	// barcode image margins
	barcode.setLeftMargin(0f);
	barcode.setRightMargin(0f);
	barcode.setTopMargin(0f);
	barcode.setBottomMargin(0f);
	
	// barcode image resolution in dpi
	barcode.setResolution(72);
	
	// disply barcode encoding data below the barcode
	barcode.setShowText(true);
	// barcode encoding data font style
	barcode.setTextFont(new Font("Arial", 0, 12));
	// space between barcode and barcode encoding data
	barcode.setTextMargin(6);
	
	//  barcode displaying angle
	barcode.setRotate(IBarcode.ROTATE_0);
	
	barcode.drawBarcode("C:\\code128.gif");
