Java Code 128 Generator Data Encoding Tutorial

sample source code to input valid data and generate linear Code 128 images in Java

• Code 128 barcode can be set in the center, right or left of the image
• Code 128 image color can be changed with setting BackColor, ForeColor and TextColor
• The generated Code 128 image resolution can be set to be a fixed value with your need
• Java Code 128 generation component supports rotating Code 128 image with 0, 90, 180, 270 angles
• Encoding Code 128 valid data set to generate valid Code 128 images in Java applications
• Set proper data length to generate and create valid Code 128 barcodes in Java applications
• Completely developed in Java for any operating systems with Java Virtual Machine
• Pre-configured industry standards Code 128 allow any untrained users to insert Code 128 in Java
• Java Server Side projects (JSP, Servlet, EJB, J2EE, Web Service) can be easily integrated

Java Code 128 is an important linear barcode generation dll for outputting high quality Code 128 images in Java projects with full setting property.

Java Code 128 size setting focus on Code 128 bar setting, space setting and margins setting;

Java Code 128 image setting pay attention to Code 128 avialble data set and data length.

Java Code 128 consists of applets which may be used to easily display barcodes in Web pages with compatible Web browsers. About 50 properties are valid for adjustment with all kinds of need,such as size setting for Java Code 128; image setting for Java Code 128.

Code 128 Introduction

Code 128, also known as ANSI/AIM 128, ANSI/AIM Code 128, USS Code 128, Uniform Symbology Specification Code 128, is a very effective, high-density barcode symbology which allows the encoding of alphanumeric data. It is designed to encode all 128 ASCII characters and the Latin-1 characters defined in ISO/IEC 8859-1.

Valid Digit Set to Encode Code 128 in Java

• Uppercase Letters: A - Z;
• Lowercase Letters: a - z;
• Special digits:- (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus);
• Numeric Digits: 0 - 9.

Valid Data Length for Code 128 in Java

Code 128 generator for Java can encode any data legnth with any valid data set to output Code 128 images in Java.

Encode Only Numeric Data for Java Code 128

Code 128 generator for Java is able to be encoded with only numeric letters in Java projects from 0 to 9 with variable data length.

      Code128 barcode = new Code128();

      barcode.setData("128128128");

Encode Only Uppercase Letters for Java Code 128

Code 128 generator for Java is able to be encoded with only uppercase letters in Java projects from A to Z with variable data length.

      Code128 barcode = new Code128();

      barcode.setData("JAVA");

Encode Only Special Digits for Java Code 128

Java Code 128 generation SDK can encode only special letters which are - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus) to draw Code 128 image in Java class.

      Code128 barcode = new Code128();

      barcode.setData(":/.+");

Encode Only Lowercase Letters for Java Code 128

Code 128 generation component in Java can encode lowercase letters from a to z for Code 128 image generation.

      Code128 barcode = new Code128();

      barcode.setData("dataencoding");

Java Code 128 generation component is compatible with any number of data using Java.

      //For 6 digits to be encoded
      barcode.setData("Code39");

      //For 11 digits to be encoded
      barcode.setData("Java-Code39");
